I am trying to find out about a William Henderson who married Isabella Andison 24 july 1807 in Southdean, Scotland. They lived at 10 Oliver Park, Hawick, Scotland I think. Children were Adam b1809, Andrew b1811, Mary b1812, Margaret b1813, Betty b1817, James b1821, Agnes (Mrs Beattie)b1824, William b1827, John b1831, Thomas b1832. Any information on William's parents and siblings, marriages of his and Isabella's children would be great.
