Alexander STEWART, b. ca. 1791, Cambusnethan, Lanark; m. 8 Oct 1814, Cambusnethan, Jean WALKER, d. after 1861, 7 children. Who were his parents?

John STEWART, b. ca. 1787, m. 13 May 1810, Lesmahagow, Lanarkshire, Janet TENNANT. Daughter Jane b. 1813, Hamilton, Lanark. Many children in Ayr and Renfrew with these parents' names, but I think they are other couples. Anyone know where they went after marriage? Did they move to Cambusnethan to be near their daughter?
