Eileen Mary Sellars, dau of James Sellars, electrical engineer married an Australian pilot Philip Hugh Boulton at Hastings, Sussex on 30 January 1940. He told his father in a letter that she was 19 years old and a Roman Catholic, while he was C of E. Her husband was killed in action in 1941 and is buried in the Hero's Corner of Alperton Cemetery in London. We believe that Eileen Mary Boulton nee Sellars may have remarried after the war and it's also possible that she died quite young. (Family legend says so.)
The family in Australia has a photo of Eileen tending Philip's grave post WW2, accompanied by her unnamed son. He looks so much like Philip Boulton that we wonder if this boy was Philip's son. If so, he'd be the last in his line of the Boulton family and we'd like to find him or his children, to pass on many family stories, letters etc. I have many pictures of Philip Hugh Boulton as a baby and young child and have written a book using the Great War letters of Philip Hugh Boulton's father, Dr Nigel Philip Boulton. The child with Eileen in the post WW2 photo may not be aware of his Boulton heritage if his mother remarried when he was young, but he presumably knows his mother's maiden name, hence the heading for this topic.
My specific question at this point is this - from Free BMD, the birth of an Eileen M Sellars is registered in Driffield in the Dec Qtr of 1920. Does anyone have a parish record of the (Catholic) baptism of this child, showing her name as Eileen Mary, father James, with an occupation related in some way to electrical engineering? If I had specific details of her birth, I'd have a better chance of tracking her in later life. Instead of just purchasing the birth certificate, I'm posting this as a question, hoping that the full message might eventually be found by Eileen's descendants.
