On the ship roster, she and her father are listed as McChrystall. In researching the name, I read that it is originally Scottish and means "son of Christopher." Has anyone come across this surname, and does it belong to any clan? Aloha, Kathleen Choi >> MacCrystal - son of Cristal or Chrystal ( Lowland Scots diminutive of Christopher) I also have a referene which links the name to the Buchan District. There is no official Clan affiliation.
