Hi Joyce, My Thomas Allison was born 1823. He married Mary Smith about 1843. Unfortunately, I know nothing about Mary. Their children were John Allison (b 1844), Alexander Bailey Allison (b 5 Dec 1845), and Mary Palleen Allison (b 30 Apr 1846). Thomas then married Rebecca Goddard in 1849. They had Bell Allison, Virginia Allison and Keziah J Allison. I hope this information helps you. Marian
