I have a William Laird Adam/Adams who was born in Scotland and wound up in the Santa Clara/Santa Cruz area of CA, and married Elizabeth O'Connor who was born in Qubec Canada either late 1830's or early 1840's. She was the oldest child of James and Mary(Kell)O'Connor . She had 7 sibblings I think. William's mothers name was Isabell and she was a Laird
If any of this sounds like it fits, let me know I have tons of inf on the Adam's, O'Connors and connecting families in CA, Nothing really on their life in Scotland though.
