Have you made sense of this 1841 census?
www.scottishindexes.com/41transcript.aspx?houseid=79003053Was Andrew Stevenson connected to Betty's mother? With Betty showing as 25-29 in 1841, hard to say.
Did Betty go on to have another child showing as 2 months old in 1841? She would not have been aged c. 16 when she had Thomas, more like c. 18-20?
Is this Betty in 1851:
Betty Beattie 37 Formerly House Serv b. Hobkirk
Infant 10 Momths son b. Hobkirk
Address: Greenriver, Hobkirk
John Gray also showing with Thomas in 1851, both down as newphews to Andrew Stevenson. Have you managed to follow through on Andrew Stevenson to establish his parents' names? What about Betty? Have you post 1855 certs that help you in confiming her parents' names?
I could only see one James Rutherford in 1841. A joiner, aged c. 60 with family. Did he have a son by the same name?
