Hi Gortraney,
I’ve just come across your post. My great grandpa was Bobby Wylie, and great granny, Grace (neé Dobbin. Their son, Robin, who you mention informing of family deaths, was my Grandpa. Robin passed away in 2005, and had three sons, with my Granny, Olive Isabel (neé Porter), the oldest of whom is my Dad.
I met Matthew Anderson Wylie (my great uncle Andy) at his farm in Ballygowan when I was a young girl in the 1980s, he passed away in the early 80s from memory.
There are definitely some family photos we have, which now Robin and Olive have passed, we’re not quite sure who they’re of, so one could be your father.
Hopefully you read this, as your post is from quite some time ago.
