My great uncle and great aunt (brother and sister) worked on our family tree for years. They were able to track it back to our first ancestors that arrived here, sometime in the 1600s, I believe. He has compiled at least two or three hefty printed and bound volumes. He did ask to be reimbursed for his printing fees-I believe about $10 per volume? He is currently working on the third or fourth volume. I have absolutely no problem reimbursing him for his fees.
