I started this family tree after several unsuccessful searches for my great 
grandmother, Sarah Ann Macdonald/Lockerbie parents. I have found a few trees 
with Sarah & Andrew Lockerbie and their children, believed to be traced from 
the Lockerbie side as Sarah's brother Alexander married Isabella Lockerbie 
with their children are also listed. They had a brother Simon whom I have not 
found in any of the family trees.
