My great grandfather was james Patrick Carroll, b.?, d.1921?, Jersey City NJ where he lived with his wife Janet (Cowan) Carroll. They had three children, David William Telford Carroll, b. 1893, d. 1957, Hazel b.?, m. Sylvester Parker, NY, and another daughter. I am looking for any antecedents. Family rumor has James Patrick emigrating from Ireland and Janet Cowan from Scotland, but no reliable information. Any help?
