From his War of 1812 papers, we have that our Justus J. Perigo was born 1768 in Pownal, VT, mustered out at Sacketts Harbor, NY. I see you have him as a probable son of David, & it is good to have a probable parent for him. Can you tell me what makes you think Justus belongs to David?
For any help it might be: Justus was injured in the war & received land in what became Adams Co, IL. He is listed in the histories as the first settler there. We have much on his descendants - need his ancestry.
Those war records say he had dark complexion, which goes with the French name - presumably at some time in the past from Perigeaux, France (a large town in the Dordogne where I visited). We have wondered where our olive complexion came from in the otherwise Scandinavian ancestry. And our elders said a French-Canadian ancestor.
Also, interestingly, French Minister Talleyrand-PERIGORD! - Jefferson bought Louisiana Territory through him.-( in Landon Jones, William Clark and the Shaping of the West, p 111 )
Your careful research is much appreciated. Thank you. E. Bennett
