I proposed an unmerged match between Pollack-398 and Pollack-437 on 30 Aug 2019. S J Baty's question about General Arthur St. Clair inspired me to return to Martha Pollack, concerning the father of her son Samuel Robb (a possible cousin). Samuel married Louisa St. Clair, the General's daughter. The father is thought to be James Robb Robb-1790 but this is not proven.
The two profiles of Martha don't have verified information on the places of her birth and death. Pollack-437 has Westmoreland County and I proposed Chester County for Pollack-398 only because that's where the Robb family came from.
Samuel Robb's profile Robb-1932 has a newspaper article attached that references a biography by John Meginness of General Arthur St. Clair's family. The same John Meginness wrote "Otzinachson: A History of the West Branch Valley" (1857) and "The Life and Times of Robert Robb, Esq." Robert Robb was a brother of James Robb, Samuel's presumed father.
Can anyone help to find sources for a possible connection between the two profiles of Martha Pollack?
