:That's very interesting. Thank you very much for looking that up and sharing it. 

 :My view has long been that biographers have been too trusting of some of Croghan's claims. Many historians comment on Croghan's various land schemes and apparent flexibility about telling the truth, and yet they report as fact various claims for which Croghan is the only witness. Croghan claimed to have been appointed a Six Nations councillor in 1746 and to have been granted 200,000 acres by the Six Nations in 1749. Unlike the historians, I've been skeptical of these claims, although I certainly haven't seen all of the documents. Lately I've been wondering if these statements by Croghan are fictions invented to claim some land before the Ohio Company and Vandalia big shots got all of the prime real estate. 

 :But I'm certainly taking your idea seriously. Here's more support for your theory: on at least one occasion, Croghan reportedly claimed that he was an Indian! During the 1758 Treaty of Easton, a Quaker (perhaps Charles Thomson) said that Croghan "gives out that he himself is an Indian". (Thomson's complete pamphlet is online from the Internet Archive.) Historians haven't paid any attention to this claim, I think, seeing it as another one of Croghan's schemes to get Indian land. But your theory puts this in another light, of course. 

 :And finally, Croghan biographers bemoan that they could never find the name of Croghan's mother, even though she was in Pennsylvania and living with him. But if she were an Indian, the historians wouldn't have connected a Native name with Croghan's mother. Hmmm. —
