Huge thankyou to everyone who helped find these ladies. I'd just like to explain my interest in them.
I'm working on a possible connection to my gt grandmother Mary Ann Lane. Born in the Union workhouse at St John Horsleydown to a Hannah Lane in 1871, she was illegitimate and the Metropolitan Archives have no extant records covering this year for this workhouse. She spent all her life in the Southwark area. She is missing on the 1881 census and is married by the 1891 census. I can find no convincing baptismal record for her.
Hannah, her mother, is a mystery. I have no way of identifying her so I'm having to take a lot of speculative long-shots starting with women who would be of child-bearing age in 1871 who were living reasonably close to Mary-Anne's place of birth and trying to work backwards and forwards from that year to see if I can identify a possible candidate. if I do find a possible I look on my DNA matches for any males living in the Southwark region in the correct year. Then I check whether any of my other matches share that same surname. It's been suggested that Hannah might be of Irish decent. I do know from my Irish ancestors that first names tended to be interchangeable - Hannah/Anne/Anna., even Johanna.
I have one tentative connection from one of my DNA matches. There tree and mine share no surnames but their family did come from Bermondsey and were licensed victuallers so women with the surname Lane working in a pub is of interest.
This may be of absolutely no consequence whatsover but I'm having to try some very unorthodox methods now as I've run out of other ideas. I thought DNA testing would help....so far, not really.
Again, thanks for all the replies. They've given me some areas to research.
