So the full story is that I'm chasing down a weak DNA match, and I'm first verifying that their paper trail to a possible shared ancestor is legitimate.
They have a Thomas Price marrying an Elizabeth Alice Cottle on 16 March 1890. No location or source given, but they lived in Battersea so Wandsworth registration district is likely. This is the family in the 1911 Census. They have a birth registered to them at gro.gov.uk in 1888, but that doesn't preclude an 1890 marriage.
This Thomas was according to this tree born in 1863 in Battersea to Peter Price but this is dubious as he doesn't appear with his parents in the 1871 Census.
I haven't been able to find a birth record at gro.gov.uk with the right mother's maiden name which is another red flag. Not like I haven't found numerous cases of un or mis registered births over the years, but red flag nonetheless.
But to be thorough and to give the original tree creator the benefit of the doubt I'm looking for the marriage record of Thomas to learn his father's details.
Sorry I didn't give more detail, I thought this would be straightforward!
Thanks for your help and assistance.
