I'm not a real planner; I'm more the rabbit hole kind of guy. I like to do unsourced profiles, generally Connecticut from the early days through the 18th century. When I find a birth source, for instance, often from the Barbour Collection, often parents' marriage dates show up, as do birth of siblings. Well, I just can't ignore that data, can I? So I have to add them, or at least add sources for them. Then I notice a sibling's spouse and I have to add that! Then I find that adding a source discloses a duplicate profile I have to merge... 30, 40 windows open at once? No problem! But it sure is fun!
