Who is the mother?

Wow, brilliant!!
I will have to take my time and go through all this and compare it with what I have. 
I do have that Thomas's father George was married to Mary Gibson and George Birrell was married to Mary Elliot.
And thank you for finding Jamsie for me too!  I would never have guessed Jemima.  And another son too.  Between 1809 and 1821 there must be other children to be found. 
What I'm not clear about is if the dates are transcribed correctly, Thomas was born in 1765 and yet had a son in 1821 (and obviously didn't die in 1819!)  and was a lot older than Sarah - nearly 20 years older.  Unusual but not impossible.
This has really given me something to work on and I'm really grateful for the fact that I haven't got to delete all the Birrells from my tree!
Many thanks to all and I'll get back to you with my findings.

As always brilliant help for you on here.. 

The Birrell name is what has kept me interested...

deep in the depths of my tree I have a George Birrell  but probably .. not connected ..

There are lots and lots of Birrells, seem to be concentrated in the Gretna area.  I have three Georges
