Hi Leanne,
Sorry, I'm getting mixed up as to who's children were whose!
The children listed above - are they the the children of Robert Lang & Elizabeth Mitchell?
I found the births of 11 children in total born to John Laing & Barbara Laird between 1799 and 1824. Third child Mary, would she be the one whose middle name is Falconner?
I couldn't find anything for Robert Lang & Elizabeth Mitchell.
I also found 2 births to a Charles Laing & Margaret Falconner/Falkoner.
These were Jean born March 1771 in Falkirk and James born December 1773 in Bothkennar. Presumably they would have been married 1770/71
Have you read the threads posted by Dano? Have a wee look - Theres a possibility you might share some common ancestors. I can vaguely remember Dano saying that one ancestor, a Farquhar Laing was also referred to as Pharchar and Falconner, but don't take this as fact, I'm only quoting from memory.
(One of the children I found born to John Laing & Barbara Laird, their 10th child born 1822 was named Pharchar . . . . .?)
