What's a gal got to do in order to get a copy of the family tree from relatives? One of my dad's cousins researched the family tree years ago when I was still a teenager. Having a great deal of interest in my family tree, I've asked a few times since then if I could have a look see. At first it was my dad saying "Oh yeah, I'll talk to my cousin and get a copy..."
Would you consider personally contacting this DC and asked his or her pre-paid price for copying and mailing rather than relying on someone to do so on your behalf?
I'm a retired genealogy librarian. Many researchers spend decades and thousands of dollars on their project. While some (thank you, Aunt D) willingly share their results with source documents cited but copies not included, others do not. I have done my own research which runs to 2 very thick binders. (Aunt D's supporting documents runs to a filing cabinet.) It would cost a bundle to copy and mail. I would not just hand it over upon request. If a relative wanted a copy, I would quote a price, pre-paid, for copying and mailing. If someone wanted to see a binder during a visit, they are more than welcome to do so. And no, it is not available for loan.
And another thing. Just because some ancestor info is online doesn't mean it can be verified with supporting documents. Some is, a lot isn't. We always cautioned beginning researchers about that. "But I saw online that great-grandpa is descended from Henry the 8th." Online info may be able to guide you but there is no substitute for your own meticulous research. We had one researcher who believed that she needed to prove every relation with 5 different supporting documents; thereby someone who claimed that it did not exist would have to come up with 6 supporting documents disproving it. Think of it. Could you prove your marriage, your parentage, a sibling, a death date with 5 different documents? We had an otherwise very credible researcher who claimed to be descended from both Charlemagne and John the Baptist. I would have loved to have seen her stash of documentation.
Then there was our perennial favorite. "Great-grandma said I am descended from Robert E. Lee." Must be a regional thing. Well, for starters, REL's living descendants are few and known to each other. Do you know them? Second, at the time, there were at least 5 Lee families in Virginia that were NOT related to each other. So, your ancestor may have been a Lee from Virginia, but not that "Lee" from Virginia.
