brigidmac and Glen, thank you for posting your questions.
Colleen has one tree. Her tree has fewer than 15 individuals; several individuals are marked as private. I found an obituary that thankfully gives grandchildren’s names and by comparing the obituary with the tree, I believe Colleen is a direct descendant.
Actually, the man in her tree is the nephew of my ancestor, not brother, but I would think that wouldn’t change the results (she should still show up when searching for Ovens)?
My gggrandfather, John, settled in Canada in the 1850s. Due to early deaths and other circumstances, to my knowledge, there are few living descendants of John. So, not surprisingly, when searching for Ovens matches, there aren’t many: my mum has 9, I have 7 and my brother has 6.
I’ve just looked at my mum’s and Colleen’s shared matches. One match (“Annie”) is puzzling (at least to me). I don’t see any Ovens in her tree but, shown as a direct ancestor in Annie’s tree is an Elizabeth Wakefield. Elizabeth’s great-grandfather was David Wakefield. My ancestor was Jane Wakefield, her grandfather may have been David Wakefield (I have yet to find proof). The puzzling part is my Jane Wakefield married John Ovens - possibly Elizabeth’s relative married an Ovens? That will take time to research.
Thank you brigidmac, Glen and 4b2 - your questions and comments are very helpful and will help as well with other situations I come across. (I hope I’ve answered your questions.)
