I think I can help you, if you still need it. We are decended from "Baltimore John" who was born around 1670 or so (records are in basement). The story about donating the land to Baltimore, the Brooks names all correlate. I can go both directions from Chancy Brooks in the Harryman leg. Your greatgrand father George Harryman is either my greatgrand father or great-great grandfather. I met one of their decendents -- Brooks Harryman who ran a broom corn dealership/factory in Baltimore. Exceedingly nice family.
