Because my Joseph Dickson and family came to America after the 1841 census and before September 1842 (when Joseph died in Macoupin County, Illinois), I only checked to make sure that the Joseph, Margaret and Helen Dickson I found in 1841 census was not still listed in 1851. I have not gone beyond the earlier census.
The 1841 census lists Robert Dickson age 40, wife Agness 40 and sons William 12 and John Dickson 9 at Lockside. William Dickson 65 and dau. Jessi(e) 20 at Crofthead. In Springholm were, Agnes Dickson age 19 with dau. Mary Ann Kerr age 5 mos. Anne Dickson 6 in household of Andrew Armstrong and immedicately following was my Joseph Dickson 50, Margaret 40 and Helen 16. In Haugh village on was William Dickson 60, Jane age 27 and David Clark 5. Plus other Dickson/Dixons in other locations but, all in Urr Parish.
I made a copy of Enumerator's Schedule No. 3 (No. of Parish 884, Name of Parish Urr, County Kirkcudbright) which lists all the others in that particular Schedule. This is the schedule where Springholm appears, plus a few other locations. Because my copy is printed from the microfilm, some of the name are hard to read.
