Where might I look for the family papers for certain Wigtownshire families? Specifically I am interested in the following who were tutors for Patrick Coltrane's family at the time of his death (1714): John Stewart of Physgill, Robert Stewart of Physgill, Patrick Vaus (Vans) of Barnbarroch, Patrick Heron of that Ilk, John McCulloch of Barhome, Patrick Maxwell of Monreith, Alexander Agnew of Dalragle. Thank you. Dorothy Coltrin
