I am sorry for the delay in replying but I can solve part of your problem.
Louisa BLACKMORE born c. 1832/33 in Bristol went to live with William PARKER at Toveys Green Farm in Coalpit Heath as his housekeeper in about 1852.He was 56 years old at the time.In 1853 their daughter Davina (Stivina)was born and then William in 1854 followed by a further 10 children.Five of them were born deaf including Davina known as Stivie.Louisa and William were never married but the boys were known as Parker Blackmores. On birth certificates, the initial P was entered I believe so Parker was given as their middle name originally.
Some thirty years ago I visitied Coalpit Heath graveyard and a very elderly lady saw me looking at the graves of William and Louisa side by side and she said `they were the scandal of the village`. Wow!!
I have your william as marrying an Edith and they had three children - Eleanor, William and Kathleen.According to my grandmother, William was taken out of his pram by Emily Everetta, his aunt, and taken to London where five of the brothers and sisters (including my great grandfather) were living at the time and he was brought up by them. Edith was `man-mad and not a good mother` according to my grandmother as told by Emily.This William (Billy) married a Vera I believe and they had two children to my knowledge called Royston and Jeanette.
Is this your family???????????
I am directly descended from Albert born in 1859. To fill you in further, the William that was taken out of his pram committed to going into business with grandfather.At the very last moment William (Billy) backed out leaving my grandfather in a precarious financial situation made worse by the fact he had recently married and my father had just been born. The two of them never spoke again - my father met his cousin, Roy, for the first time many decades later in Burtons while waiting for a tuxedo fitting.
Louisa had four sisters and was the daughter of James Blackmore born 1790, said in the family to have been a coachman at one time.Louisa, her sisters and parents lived in Bristol in the Christchurch area and can be found in 1841 census onwards.Censuses say he was born in Monmouthshire but having found nothing, I cannot get it out of my head that he may have been born in West Buckland, Somerset purely because later generations of the family were sent to West Buckland School in Devon - the 4th generation is presently at the school even now.There was a James born in 1790 in West Buckland who married a Jane and had a daughter called Louisa.I cannot substantiate this is my James.If you have any luck then let me know.
