Katie-I don't have too many CARTER's in my database. However I do see them connected to the MCROBERT line as well as the LIGON line. The LIGON line connects to the WOODSON line which is well documented. The WOODSON line, of course, connects with the MCROBERT line.
I have cousins that are interested in genealogy also. My grandmother shared with us, from the time we were little, and it soon becomes apparent which children are really interested and which ones aren't. Those of us who are become the keepers of the history for the generations that follow.
Missouri is definitely in the family tree,though!
