Paul,
I did get your email and I have emailed you back. I have lots of family tree information, our grandfather Fred Tucknott was born to an unmarried mother and hence he was given his mother's maiden name which was Tugnutt. Over the years the names Tucknott/Tugnutt have been used interchangeably, a pain for research. Fred & Amelia (both of whom I knew well until their deaths in 1986 and 1980 respectively) had 10 children and I have known all of them throughout my life except for your father. I know why that is the case, email me back on my personal EMail and I'll tell you what I know about the Tucknotts and Tugnutts!
Dawn.
