Start with the chain you need to prove
Most descent claims require an unbroken documentary line from you to the qualifying ancestor. In practice that means a certified birth certificate for every generation in the chain, marriage certificates wherever a surname changed, and death certificates where relevant.
Work backwards and write the chain down before you order anything. Knowing exactly which certificates you need prevents the most common waste — paying for records that turn out to be irrelevant.
- Your full birth certificate (the long form showing parents, not the short extract).
- Your parent's birth and marriage certificates.
- Your grandparent's birth certificate, and marriage certificate if the surname changed.
- Death certificates where a link in the chain has died and the authority requires it.
- Legal name-change documents, deed polls or adoption orders for any discrepancy.
