Thanks for the reply. This has finally confirmed I have the right family.
For you information the details of the first marriage of James Deakin are:
He married a Maud Alberto on the 23rd December 1937 at the Parish Church, Saundby which is near to Gainsborough. At the time of the marriage his address was shown as 84 Vessey Road, Worksop. His fathers name was shown as William Deakin. The marriage certificate records him as been 44 year old bachelor and Maud Alberto as age 23. Based on this it would have made his year of birth either 1892/1893 but I have since clarified his actual date of birth was 11.12.89. We think this difference may be that he took a few years of his age when he married because of the age difference.
My father was born on 1.10.38. and is a Michael Frederick Deakin. Apparently my Grandma left James Deakin when my Dad was three month old and went back to live with her mother. I did find a record of a James Deakin age 49 living by himself at 45 Manton Crescent, Worksop in 1939 which seems to tie in with this.
My mum and dad married on 4.5.63. at Holy Trinity Church, Gainsborough and his home address was still showing as Saundby. They had two children myself born on 10.2.66. and my brother born 13.4.68. ( I can let you have the full family tree if you want it).
If you could let me have details of the Deakin family tree that would be really useful.I have found ten other possible brother/sisters but perhaps not all of them survived. They are: Annie, Gertrude, Selena, Maggie, Willis, Doris, Hilda, Arthur, Ada and William one of whom I assume was your grandmothers brother.
Do you know if there is a grave anywhere for William and Mary Deakin? Possibly in Kiveton Park?
Do you have the dates James Deakin and Florry (Florence Deakin) married and died? and if there is a grave for either of them possibly in Worksop.
Do you know the name June Shepherd as someone of that name has put a family tree of the Mills family on Ancestry UK with a photo of my Grandad and this is, so far, the only picture we have of him (James Deakin).
Are you aware of anyone around who would remember him/have any photo's etc.
Sorry for all the questions but your response has confirmed I am on the right track and I would like to get details for my dad if I can.
I am planning to go to Kiveton Park/Worksop to see what I can find out but any information you may have may help us narrow down the search.
Thanks again for you help
