Hi Jennifer -- sorry for the slow reply. I somehow missed your post on the Board way back in July.
Your grandfather, Frank Alfred, was the son of my great-aunt, Alice Louisa IDDENDEN. She was one of the sisters of my maternal grandmother, Kate.
Some years ago, I had a bit of correspondence with your uncle Ross who told me, among other things, that he had a brother named Glen.
Please contact me directly to exchange info (click on my name on this Board to get my e-mail address). I'm also in Canada. Regards, Andrea (on Vancouver Island)
