James McIntosh Drysdale (s/o Charles Drysdale and Helen Carmichael) married Elizabeth Yeadon of Canada 1819-1854. Elizabeth was the d/o William Yeadon 1795-1849 and Elizabeth Drysdale. William was the son of John and Elizabeth Yeadon. I don't know if this line started in England or not. I do know that Elizabeth and James McIntosh Drysdale lived in Nova Scotia Canada.
