Hi there,
I am looking for a marriage of William Aitken to Henrietta Petrie on 23 August 1820.  On the 1841 census, it showed William Aitken as being 45, making him born in 1796.  I am looking for his parents names.  
If I take into account that the ages were rounded, then there are two William Aitken's born in 1801 in Falkirk, with 2 sets of parents.  If I take it as him being born in 1796, then there is one set of parents, being Thomas and Jean. 
Now, William's 2 sons were called Thomas Hamilton Aitken and Thomas Alexander Aitken.
I am a bit confused.  Can anyone help me out here?
Regards
Jackie
