Hi, Linda -
are you the daughter of Arthur and Elizabeth Luhn, sister of David? We corresponded briefly years ago (like 1980s). My father was Gordon Luhn, Arthur's brother. I corresponded with David for a while, too.
Even if you're not THAT Linda, I'd still be happy to share information with you. My father was the son of Arthur Price Luhn, son of Randolph and Sarah Luhn.
