My greatx3 grandfather was William Warren House and who married Harriet Baxter in Pittsburgh in 1818…..this is all the info I have other than the writer of the attached bio indicates his mother was a sister to Gen Warren. The info I can find on Gen Warren including a query to the Gen Warren Chapter of the DAR indicates he had no sisters. Does anyone have any info that might help? I wonder if William Warren House’s mother was perhaps a cousin to Gen Warren or if it was fashionable to claim decent from Rev War heroes….
