Hi CF
You have marked completed but just wanted to add that there are entries showing on the 1891 and 1901 censuses for Upper Drum(s), Falkland. In 1891, a farmer Peter Barclay showed there with wife, daughter and 3 servants/labourers. Again, 1901, seems to indicate a farm, with a large household headed up by a William Collier. Also a further household headed up by a Louisa Collier, with three young children.
