Searching for the birthplace, parents and siblings of Thomas Nisbett. Born approx. 1816 in Ayr Scotland. His fathers name was Robert and he was a clerk at Dean Quarry in Kilmarnock. Have found Thomas in later yrs census in England but with no luck finding any family.Once old enough to work he was a gardener and believe he worked at the estate of the Duke of Portland in Ayrshire, as he ended up at working in England as a gardener in the same locationn where the Duke of Portland also had land holdings. I am visiting Edinburgh next month and also plan to visit the library in Ayr. Any suggestions as to how to proceed? STUCK IN CALIFORNIA. Thanks in advancee.
