I am looking for information about Catherine Sinclair who married John Rosie, 25 January 1828, Wick.

I have considerable information about John but having difficulty finding anything out about Catherine other than a Peter Sinclair, cooper in Wick, who stands for her on the marriage certificate. Was he her father, who was her mother and did she have brothers and sisters.

Kind regards

Kathleen Todd (nee Rosie)
