This is just brilliant. So you are Douglas, born 1958? I have a lot of family history and have been working on it for years. Horatio has been very illusive but I do have some stuff, mainly from the Maritime History Archive in Canada. Could we swap info? I have done my (our) family tree as text boxes within Excel, and I have loads of pages of history in Word.
I'm so pleased to hear about your father - it makes our ancestors feel closer somehow.
I lived and worked in France for many years, and have been in London since 1995, and I am Ruth, descended from your grandmother's brother Arthur Leonard Damacastria/Doncaster.
I'm so happy to hear from you!
