Hi daisymae,
A Big Welcome to RootsChat

Lovely to have you join us.
Hi also Sue and Susie. Looks like you hardly need me here. Great work.

I had found the 1841 and the possible ships arrivals to check before I left. Also noted the births of James, George and William are listed on the IGI along with the extracted of the marriage of
Alexander
SNADDEN = Mary
BENNIE 30 Jun 1826 Muiravonside, Stirling.
It is common in Scotland for a woman to use her maiden name (or alternate between her maiden and married name) I believe the children are with their mother in 1841. You can access the entry at

Here are the passenger lists of interest which prove what you have already worked out.
