Re large families and possible "gaps" with likely elusive bps to find....
My oral history gave me that a particular rellie was one of 17 children. And so he was, but also so he was not ! ...
It turned out that there were 17 children all raised together as though they were siblings (17 + some infant deaths). In fact many were siblings and of course many were simply double first cousins ....
Fred and Jack were brothers with each other (they had the same parents ... Tom and Eliza)
Hannah and Mary were sisters with each other (they had the same parents .... Bob and Sarah)
Tom and Eliza's farm was next to Bob and Sarah's farm. They were in a remote outback location in NSW, Australia, no neighbours for miles and miles. These two couples had emigrated from Somerset, arriving NSW 1840's...
So eventually the boys grew up, so too the girls. Then Fred married Hannah and Jack married Mary
Fred and Hannah lived in one wing of a farmhouse and Jack and Mary lived in the other wing of that same farmhouse, and the farmhouse occupied land across both "borders" of their parents properties and all these kids had only FOUR grandparents between them. Between those two couples there were eventually 17 children all under the one roof. This was NSW in the mid to late 19thC.
Is it possible that a similar circumstance was happening in Dee's tree back in the early 19thC
Sorry if I am sidetracking you all....
