I have an Isabella Wrighton born in 1852, parents John and Elizabeth. Isabella's birth record says her mother's maiden name was Cass. GRO: WRIGHTON, ISABELLA CASS GRO Reference: 1852 M Quarter in OF KNARESBRO Volume 09A Page 109 and her Baptism names John and Elizabeth Wrighton as parents. Isabella Wrighton Baptism Date: 18 Apr 1852 Baptism Place: Spofforth, All Saints, Yorkshire, England An A-site Family Tree has an Elizabeth Bennett marrying John William Wrighton but I cannot find that marriage, nor one for an Elizabeth Cass (or ?Carr). Since the first child seems to have been born about 1835, I assumed the marriage was before that or shortly after. But NOTHING! Detective work please!
