Hi Eileen
There's not much more on IGI than you have probably found:
Marriage of Thomas and Janet PATERSON, James's parents:
THOMAS PATERSON Spouse JANET PATERSON Marriage: 09 NOV 1745 Mosshouse, Melrose, Roxburgh, Scotland
Siblings showing for James, including James's entry:
1. MARGARET PATERSON Christening: 08 DEC 1755 Melrose, Roxburgh, Scotland
2. AGNES PATERSON Christening: 07 NOV 1758 Melrose, Roxburgh, Scotland
3. THOMAS PATERSON Christening: 21 AUG 1750 Melrose, Roxburgh, Scotland
4. JAMES PATERSON Christening: 23 OCT 1746 Melrose, Roxburgh, Scotland
5. JANET PATER Christening: 13 FEB 1748 Mosshouse, Melrose, Roxburgh, Scotland
All of the above entries are submitted with the exception of James's Christening which is an actual extract from the OPRs.
The only children showing for James Patison using the batch code on IGI for Oxnam are the three you have:
1. THOMAS PATTERSON Birth: 11 JUN 1771 Oxnam, Roxburgh, Scotland
2. JOHN PATTERSON Birth: 19 JUN 1779 Oxnam, Roxburgh, Scotland
3. ANTHONY PATTERSON Birth: 22 MAR 1777 Oxnam, Roxburgh, Scotland
All actual extracts from the OPRs. Likely to have been more children, but without knowing if they moved around Parishes, I have only searched in Oxnam and these three are all that show, registered in the name of the father only.
In respect of James's wife, nothing of substance shows for her. I would say that it is more likely her surname is Hall. Lots of entries show for that name, none at all for Hull.
Regards.
Monica
