My Grandmother wrote a rather extensive and well researched geneology. She self-published it in 1970, and I have the only remaining copies that are known. It does not bear a copyright notice, but if it did, it would have passed to me. I have scanned it to a PDF, redacting certain living people's data and securing it so it cannot be edited. Is it possible to post this somewhere on Wikitree? I tried to post it to her profile, but could not figure it out. It is about 72MB scanned. How best to proceed?
