I agree that the website I am quoting from is in itself not a valid source because it does not include a citation for the text of the will. I am assuming, however, it is probably accurate given its specificity, and I am trying to find a source for the actual will. I have other sources, however, that I believe are adequate for connecting the dots between Celia Hancock, Benjamin Hancock, and William Hancock. If more knowledgeable folks feel differently, of course, I will bow to their experience.
