Hi, I'm relatively new at this family tree business and I would be grateful for any pointers in the right direction. I am searching for any information regarding my grandfather's (John Edward Calderwood) family. I believe that his father was Edward Calderwood, who moved from either Perthshire or Ayrshire in Scotland to work at Harland & Wolf, England. I believe that Edward's wife was called Margaret Mc ? Any information would be much appreciated, thank you.
