Thomson Family-revised

[TonyT]

I am trying to find who the parents of George Thomson were.
George Thomson (b-abt-1798)
married Catherine Cochrane.
Catherine was c-29 JUL 1798 at Lochwinnoch, Renfrew
I believe Catherine's parents were, Hector Cochrane and Katherine McLean
From the IGI records I have found the following information.
George and Catherine married on 16 May 1822 in Lochwinnoch, Renfrew.
As far as I can tell, they had the following children;
1.William Thomson -c-29Jun 1823 in Lochwinnoch
2. Hector Cochrane Thomson -c-21 Nov 1824 in Lochwinnoch
3. George Thomson -b- 18 Sept 1829 in Old Kilpatrick, Dunbarton and c-04 OCT 1829 - Old Kilpatrick, Dunbarton
4. Margaret Thomson -b- 5 July 1831 Barony, Lanark
5. Catherine Thomson -b-15 Dec 1833 Barony, Lanark
Any information on this family or where I might be able to find records on them would be greatly appreciated.

Thanks, Tony
