John married Sarah Kirkpatrick 1834 in Dumfries-shire, Scotland and , as yet, I've no idea when she died. However, John remarried I believe about 1852 to a Margaret Campbell (at least that's the surname I've recorded) although checking my records I don't appear to have a reference. Their children were Sarah Marion, Henry and Joseph. There was also James b.1849, now I'm not sure if he was Sarah's last child or possibly born out of wedlock to Margaret Campbell/Jackson! It would appear he was born about the same time as John junior.
