Grace Henderson/Wilson

Hello, I am looking for any information about Grace Henderson and her husband Robert Wilson. I don't have much to go on. Their children were William and Mary (may be others).  Mary, my GGGrandmother, was born about 1820 in Enniskillen. She married John Wilson and had a child, Susannah born 17 Mar 1838 Enniskillen. There may have been other children. Mary Wilson (widow) was tried 4 Mar 1850 Cavan and transported to Hobart Tasmania, with Susannah aged 13, onboard the John William Dare 28 Dec 1851. I would be grateful for any information.  Many thanks. Susan Hanmore
