Hi Bruce,
So glad you've posted your message on RC. It's been so long since I've had time to look at my family history 'stuff' - it's made me look it all out and got me enthused again! I too have a copy of the will you're after, which shed light on John Anderson having a 2nd wife Janet Rae (b. Shotts 1797). Janet Rae and John married 30 Jan 1831, their children, John Rae, Peter, Christian and Janet (but you possibly know this already). Interestingly, whilst John Rae became Mayor in Illinois, John's (rural postman in Bathgate) son to his first wife Janet Binning, Smith Anderson, became Lord Provost of Kilsyth in the late 1800's. That Smith Anderson is my 2x Great Grandfather. Will send you a personal message as I've other things to ask you.
Kind Regards,
Lesley
