There is a pending merge on this historical figure that would introduce a second wife and previously unacknowledged (by Geni) child. Since I don't find any proof for it, I'm inclined to remove it. But I'm concerned that someone else might merge it in the future, or, that I'm mistaken after all and he really did have another wife. The dates don't seem to make sense, though (at a glance).
