However, there is one very additional piece of information of on that same marriage certificate. His father is noted as Robert Paton, deceased but his mother was still alive and none other than Jane Bain. She on that 1871 census is recorded as aged thirty-two, so born in 1839 and in Glasgow, with her husband just twenty-six. It would mean that, if Bobby were not actually a "boarder" but her son, she would have had him aged just fifteen, he presumably illegitimate. Furthermore still in 1871 John and Jane Bain had several Bain children, the eldest of whom was five. But the couple had only been married in Jamestown in 1868 so at least one of their children had been born out of wedlock and, moreover, she, recorded on that wedding day as Jane McMahon, is aged 28, so again born in 1839-40 and still fifteen on Robert's birth. But there is a complication. In 1861 a Jane McMahon is recorded in Bonhill but she is aged twenty-six, which means, if they are the same, she lied on the her marriage and for the 1871 census, was actually born in 1834/5 so was nineteen on Bobby's birth but with still illegitimate.
