I spent several hours yesterday entering data from research on the LAIDIG family that a cousin (first cousin, twice removed) had done previously, and before I knew it, I ended up with eight generations! I've only entered two or three pages of Jere's research so far--there are many pages to go.
And then I have research on the HELZEL line from an uncle, and research on the WELLINGTON line from another cousin (also a first cousin, twice removed in the same direction--that generation must have been particularly into genealogy!) and as-yet unacted-upon contact information for the DEAM line that should lead to a wealth of data there as well. Whew!
PS - Just in case you're curious, here is a page that explains how to determine cousin-ness. In both of the cases mentioned above, the common ancestor is my great-great-grandparent and the cousin's grandparent. Thus first cousins, twice removed.
