Mike, you asked about Jeremy and Sheila's birth parents.
We know that Sheila’s natural mother was Christine Jay, the daughter of Canon Eric Jay, a one-time senior chaplain to the then Archbishop of Canterbury. Her father was an unknown cleric or theology student, someone of that sort.
For me, part of what's interesting about Sheila's parents is:
1. Sheila's father's identity seems to have remained a well kept secret. I imagine Sheila learned who he was when she met her birth mother for the first time shortly before her death? Yet little or nothing ever seems to have leaked out about him. I wonder why? Was he considered a bad chapter that was best kept firmly shut? Or was this to protect him and his reputation? There are lots of unanswered questions about thsi man. Was his name on Sheila's birth certificate - was he even aware of her birth, let alone her death? Did her attend her funeral? A number of people let poor Sheila down, was her birth father one of them?
2. Sheila's maternal grandfather, Cannon Eric George Jay, was the son of a hosiery assistant who lived in Tiptree. Eric was born in Tiptree in 1907 and lived just 10 minutes drive from WHF where Sheila died. I wonder did he know the Bambers and religion obsessed June in particular? Did he know of Sheila's death and did he attend her funeral?
3. Sheila was adopted anonymously via the children's society yet, there's her grandfather, born and living just up the road from the Bambers. Sheila was also born in Gloucester, where Robert Woodiwis Boutflour lived and worked and where Nevill had been a student.
it's a small world, isn't it?
