Hello Viv. What Melrose surnames are you interested in, if I may ask? I've done a lot of research in the Melrose records myself, including the Melrose Regality Records, where there are many entries for the surname Moffat. As far as I can see, the Moffats were one large extended family, with concentrations in the fermtouns of Threepwood, Ouplaw and Blainslie. They go back to ancestors who were "kindly tenants" of the monks of Melrose Abbey before the Reformation, i.e. farmers who were regarded as having farmed the same place time out of mind, although they had no written entitlement to their lands.
My most recent Moffat ancestor was my great-great-great-grandmother Alison Moffat (b. 1779, Ouplaw). She never married, but had an illegitimate son called Robert Stephenson, my great-great-grandfather. Robert and his wife Isabella Wight (from Maxton) are buried in Melrose Abbey churchyard, where they have a (broken) headstone. You may know already that the monumental inscriptions of that churchyard are available on CD.
Alison Moffat's brother William, farmer at Newstead, has descendants at the present day.
