Many thanks for replying. My father was born over a hundred years ago (I was a VERY late baby!), and seems to have had a colourful life. I'm fortunate not to have had your experience, as this chap claims not to have used Ancestry, etc, but to have gone to one specific online tree (he searched for our surname and went from there). I have followed the advice given earlier on here, and have asked him for details of my father's appearance, distinguishing features, etc, which I remember but his family might not, if this isn't a genuine genealogical query.
