Hello fancy nancy,
James Hepburn and Margaret Douglas were my GGGG Grand-parents through their daughter Margaret Hepburn (born 22 Oct 1813 Cambusnethan, married to Thomas Smith, died 03 Mar 1893 Whitestripe, Newmains). Sorry, I don't have any info on Janet and William Boyd. The only other info I have on James and Margaret is that he was a Coal Miner. Do you have anything on their births, marriage or deaths, or their ancestors?
Canisp.
Edit - Just found James Hepburn and Margaret Douglas married on 29 Oct 1808 Cambusnethan, and had 6 daughters - Catharine 1809, Jean 1811, Margaret 1813, Janet 1815, Helen 1817 and Mary 1820. Any other children?
