I was just taking a quick break for lunch and decided to Yahoo! search for my surname - and I found you guys. How exciting!
I live in Yorkshire in England and my family name's oldest living holder is my octogenarian Grandfather, Harold - or Lyddy to his friends! I know he was born in 1916 in the industrial Yorkshire city of Bradford but, sadly I know very little else.
I have no idea if we might be the family line you are looking for, but if you can advise me on where to look I'll be happy to search over here from my base in sunny Yorkshire.
Take care fellow Lydamores,
