I think this is a great idea. I am sure I'm not the only one who couldn't have two-legged children. Instead, I have two four-legged children; my dachshunds, Friederich and Wilhelm. At one point, I thought about creating a family tree scrapbook page especially for the dogs and, only the dogs.
BTW, are you researching your Hickman line?
Yes, I have done research on my Hickman line, so far if I have it correct our Hickman ancestor was John Peter Hickman 1740 from Germany, migrated to Pennsylvania 7 Oct 1755 , Washington County, W Virginia and descendants on to Kentucky, Indiana and my husband's family ended up in Missouri and I married him in Ft Worth, Tx when he was in the Air Force.
If you are interested in my grandson's Ancestral Pets Page, which is still under construction you can see it at:
