Neil, Believe it or not, she told me she and her daughter drove by your place in Wyoming last summer, but was too nervous to stop in or call.She was afraid of disrupting your lives in case your dad didn't know she even existed.
The same is true with my Dad.He never knew his father.Turns out my grandfather was married at least three times, and my dad had three half brothers.By the time I was finally old enough to search (I found them the same way you did, on the internet!) all his 1/2 brothers had passed away, but now I have gotten to know cousins I never had in CA.It is strange, but wonderful! What is truly funny is how much alike we all are, even though they didn't grow up together!They have a physical resemblence, and are very much alike in personality, etc--they call it genetics!! :)
