G'day Carol,
Can't find a connection with my family, but for some years I have been in contact with Lila Finlay, in Canada, who has Lyall ancestry. I know the name is spelt differently but, maybe, there is a possibility that you are connected. She metions that the name, Isabella, comes into her family. Her email address is
finlay.lila@sympatico.ca Kind regards, Ken Lyall.
