Hi CJW
Due to the lack of info on Rachel's birth details on IGI, I've gone down Gadget's suggested route of looking at their children which show on IGI:
1. JOHN SMITH Christening: 17 FEB 1771 Watten, Caithness, Scotland
2. BENJAMIN SMITH Christening: 20 JUL 1791 Watten, Caithness, Scotland
3. RACHEL SMITH Christening: 11 OCT 1787 Watten, Caithness, Scotland
4. RACHEL SMITH Christening: 11 NOV 1787 Watten, Caithness, Scotland
5. ANDREW SMITH Christening: 20 JUN 1774 Watten, Caithness, Scotland
6. RICHARD SMITH Christening: 10 DEC 1783 Watten, Caithness, Scotland
7. SMITH Male Christening: 15 FEB 1782 Watten, Caithness, Scotland
8. CHRISTAN SMITH Christening: 05 SEP 1779 Watten, Caithness, Scotland
All entries submitted apart from No.7 above.
From this info (and ignoring any gaps in the birth years), the second born son's name is Andrew and Christian is the first girl that shows. With these two names, there is a family in Watten having children at the right time to be Rachel's family and parents:
To parents Andrew Sutherland and Christian McKy/McKay:
1. RICHARD SUTHERLAND Christening: 19 JUN 1757 Watten, Caithness, Scotland
2. SUTHERLAND Christening: 21 AUG 1752 Watten, Caithness, Scotland
3. ISOBEL SUTHERLAND Christening: 05 JAN 1755 Watten, Caithness, Scotland
4. DONALD SUTHERLAND Christening: 25 DEC 1759 Watten, Caithness, Scotland
5. JEAN SUTHERLAND OR MC KAY Christening: 03 AUG 1750 Watten, Caithness, Scotland
All entries submitted apart from No.2 above.
Pure speculation from me in the land of submitted entries on IGI!
Regards.
