Dear So and So-
When I say that the information I have comes from research other family members directly related to that line and what I could find in a casual search, I mean it.
When I say that I'll do more research into that line when I get the time, I especially mean it.
Sending me links and the like, demanding to know where I got my info- on people that aren't even directly related to you, no less, that you even admit you haven't been able to connect in your tree, as well as things I've already seen and filed away for future research and even told you as much- is extremely annoying after the 6th email.
Take a hint- that family name is NOT my direct lineage. Nor is it even a secondary lineage. In fact, other than by marriage, that line isn't even related to me. Therefor, it's not a priority to do the research on at this time. That line gets added to when I hit roadblocks in my main family lines.
And if you're trying to use my research to figure out where this particular person fits in your tree, instead of trying to do that yourself- being lazy, in other words- well, that just pisses me off. I don't mind sharing information, but you really need to make some sort of effort on your own as well.
In the mean time, your emails will go unanswered for now, because I do not have the time to do the research into that family name right now.
