I have 2 new circles with 4 members each. I am one of the four. I have the female ancestor, that one circle revolves around, as Rebecca Ann Bodden Eden. Two of the other people in the circle have her as Rebecca Ann Eden. The 4th circle member's tree doesn't even have the female ancestor, or her husband at all. (The husband is the other new circle.) The tree without the ancestors stops 4 generations before the circle ancestors. (But, in this case, both ancestors do, in fact, belong in the tree.) The 2 trees that have the ancestors & I have slightly different dates & none of us have the location written in the same manner. But Ancestry has created circles. It's interesting that now Ancestry seems to be making some leaps. We don't even need to have the same info written in the same way. Great! Right? Well...........
The female ancestor belongs to one of the earliest families of Grand Cayman. About 1700 there were only 5 known surnames in Cayman. Before that time, the Cayman Islands were a refuge for pirates & a place that ships stopped for fresh water and to catch turtles for fresh meat. There are no known indigenous native people. All Caymanian trees, including mine, have various brick walls at these 5 early surnames, for whom there are no longer many, if any, records for many individuals. I see many of these original surname brickwalls in all Caymanian trees. So, all Caymanians, whose ancestry goes back to that time are all related on many lines. Endogamy at it's finest.
My point is that Ancestry seems to be jumping to big conclusions that it really shouldn't.
