The spelling varies on different records from Isobel, Isabel, Isabella, Elizabeth. I believe she married Edward Beck. Possible children are: Edward Beck, born 7/3/1774 and Isabell Beck born 6/2/1776, Dumfries. Records for these births only provide the fathers name. James Wilson Beck born 5/19/1780 and Thomas Beck born 7/24/1781, born Tynron, lastly Agnes Beck born 5/23/1790 and Robert Beck born 5/7/1792, born Kirkmichael. The last four birth records confirm both partents names.
