I think I will start a new post dedicated to James Thomas Leslie. Several posters are descended from him and I'm particularly interested in making contact with MasonLaRoche. I have been in contact with the author of the book about the Leslies in Launceston (Tasmania) and its environs who said that tracing back beyond 1812 is impossible, She believes James Leslie was born at 5 Capel Street from the wholesaler and druggist reference you provided. Thanks a lot for your help. This has been a good introduction tho the site!
