I am David Dunlap's step daughter and I could try finding some info in my mothers things if you still need them. I did not grow up with David I was married before he married my mother but I do communicate with another step daughter of his that grew up in his household. I know I have Mary's obit. & I understand you have Dave's is that correct.
How are you connected?
I have recently moved and not for sure where my info on David & his family is. :(
and my mother passed away a year .
