Guide

How to start researching
your family history.

Start your family history with what living relatives remember and the documents in your own home, then work back one generation at a time using birth, marriage and death records (from 1 July 1837 in England and Wales), census returns from 1841 to 1921 and the 1939 Register, checking each fact against a second source.

This guide follows that route through the records of England and Wales, using The National Archives’ research guides and GOV.UK. Scotland, Northern Ireland and Ireland keep their own records, covered further down, and a surprising amount of it is free. If you are still deciding between building a tree and writing the stories, start with family history vs family tree.

Where should you start?

With yourself, and with the people who remember. GOV.UK’s family history guide gives the same first step: “gather together family memories, photos and documents” before you turn to certificates. Write down what you already know about your parents and grandparents: full names, including maiden names, and the dates and places of births, marriages and deaths. Then follow the National Genealogical Society’s advice for beginners:

  • Talk to your relatives, oldest first. Take notes or record the conversation. The Oral History Society suggests open questions, ones which need more than a yes or no answer.

  • Ask what papers survive. Certificates, family histories, Bible records and old photographs. Ask permission to see them.

  • Track every spelling of each surname. Records often spell the same family name in different ways.

  • Note where each fact came from. “Document your findings so you will know the exact sources later.”

Our guides on how to interview your grandparents and the questions to ask them help with the conversations.

How do you use birth, marriage and death records?

Civil registration in England and Wales began on 1 July 1837. Certificates for events since then come from the General Register Office (GRO), not The National Archives. For anything earlier, look for parish registers in local archives: as Surrey History Centre explains, Thomas Cromwell ordered every parish to keep a register of baptisms, marriages and burials on 5 September 1538.

  1. Find the index entry.

    FreeBMD’s volunteers are transcribing the GRO index for 1837 to 1999, free to search, and the GRO’s own online index of historic births (1837 to 1934) and deaths (1837 to 1957) is free too. The index gives you the reference to order with.

  2. Order the certificate.

    A GRO certificate costs £12.50 and is sent 4 days after you apply. Without an index reference, each search costs £3.50 extra and the certificate takes 15 working days. The priority service costs £38.50 and is sent the next working day if you order by 4pm.

  3. Read it for the next clue.

    GOV.UK’s guide explains that a birth certificate gives the mother’s name, sometimes her maiden name, and the father’s name and occupation, which help you find the parents’ marriage. Marriage certificates from before 4 May 2021 name both fathers and their occupations, taking you back another generation.

  4. Treat ages with care.

    The same guide warns that the age a bride and groom gave at their marriage is “only as accurate as they believe it to be”, so check it against a census return.

Which census records can you search?

A census has been taken every ten years since 1801, except in 1941, but names from 1801 to 1831 were not collected centrally. The National Archives explains that 1841 was the first census to list the names of every individual, so most searches begin there, although it recorded less than later years. Returns are open from 1841 to 1921, and later ones stay closed for 100 years. The 1921 census was taken on 19 June 1921, postponed from 24 April because of industrial unrest. The 1931 census was destroyed by fire in 1942.

  • Free at Kew. The National Archives shows every census from 1841 to 1921 free in its reading rooms.

  • Free locally. Many libraries, record offices and FamilySearch Centres offer 1841 to 1911 free, and the 1921 census is free through Findmypast at Manchester Central Library and the National Library of Wales in Aberystwyth.

  • Online. Ancestry and Findmypast have images and indexes for 1841 to 1921, and FamilySearch has free indexes up to 1911. In The National Archives’ words, “It is free to search on these sites, but there is a charge to view full search results and digitised images.”

Then follow one household back ten years at a time. From 1851, returns give each person’s relationship to the head of the household, their age, their occupation and where they were born, and the birthplace tells you where to look next.

What is the 1939 Register?

With the 1931 census lost and none taken in 1941, the 1939 Register is the record to search for those years. Taken on 29 September 1939, it holds details of around 40 million people in more than 65,000 volumes, and was used to produce identity cards and, from January 1940, ration books. It covers England and Wales only.

Records of anyone born less than 100 years ago stay closed unless they are known to have died. You can search the Register on Findmypast and Ancestry, both paid, or free in the reading rooms at The National Archives in Kew.

Which websites are free, and which cost money?

  • The GRO online index: births from 1837 to 1934 and deaths from 1837 to 1957
  • FamilySearch: free to everyone, with census indexes up to 1911
  • The National Archives at Kew: the 1841 to 1921 censuses and the 1939 Register, in the reading rooms

GOV.UK also lists places where you can search for free in person, such as the Library of Birmingham and Bridgend Local and Family History Centre.

Records tell you when they lived. Relatives tell you how.

What about ancestors from outside England and Wales?

  • Scotland. The statutory registers date from 1855, when civil registration became compulsory, and the National Records of Scotland puts them online as digital images on ScotlandsPeople.

  • Northern Ireland. GRONI’s online service, reached through nidirect, has a free name search that shows how many records match; full details need an account and paid credits.

  • Ireland. The Irish government’s irishgenealogy.ie lists historic birth registers from 1864 to 1925, marriages from 1845 to 1950 and deaths from 1871 to 1975.

  • The United States. The 1950 US census was released on 1 April 2022, after a 72-year restriction, and is free to search at 1950census.archives.gov.

How do you keep the stories, not just the names?

Records give you names, dates, addresses and occupations. They rarely tell you what someone was like, which is why your oldest relatives are your best source, and the one with the least time. Keep what they tell you with the records it explains: scan certificates and photos together, label them, and store copies in more than one place. Our guide to creating a family archive sets out a system.

Ancestorii isn’t a records database or a genealogy research service. It is where you keep what you find alongside the stories: a Loved One profile for each ancestor, with their dates, relationship and a life story in four chapters; timelines of dated events; scanned certificates and photos in a shared family Library; and questions sent from the app to older relatives, who answer in the app. The Free plan covers one loved one, and Premium, at £3.99 a month for the whole family, covers as many as you like. Everything stays private to the family members you invite.

No record holds a moment like this one, from our founder’s family album.

Questions about starting your family history.

Where do I start with family history research?

With yourself and your oldest living relatives. Write down the names, dates and places you already know, record what relatives remember, and gather the certificates and photos at home. Then work back a generation at a time with birth, marriage and death records and census returns.

Is the 1921 census free to search?

It is free to view at The National Archives in Kew, and free through Findmypast at Manchester Central Library and the National Library of Wales. Online, Ancestry and Findmypast let you search for free but charge to view full results and images.

How much does a birth certificate cost from the GRO?

A certificate for England and Wales costs £12.50 and is sent 4 days after you apply. Without the GRO index reference, each search costs £3.50 extra and the certificate takes 15 working days. The priority service costs £38.50 and is sent the next working day if you order by 4pm.

What happened to the 1931 census?

The 1931 census for England and Wales was destroyed by fire in 1942, and no census was taken in 1941 because of the Second World War. The 1939 Register, taken on 29 September 1939, fills part of the gap.

Can I trace my family history for free?

A long way, yes. FreeBMD’s birth, marriage and death index is free, the GRO’s historic birth and death indexes are free to search, FamilySearch is free to everyone, and The National Archives offers the 1841 to 1921 censuses and the 1939 Register free in its Kew reading rooms. Certificates cost £12.50 each, and the big subscription sites charge to view full records.
