I was looking for the relationship of Frank Reuben Rubens https://www.geni.com/people/Frank-Reuben-Rubens/6000000022914647867 to Sophie Barnettt born Isaacs https://www.geni.com/people/Sophie-Barnett/6000000007074808015. I knew they were nephew and aunt, but Geni didn't show it. I then discovered that Frank's mother Eleanor Isaacs was on two separate trees, one as Sophie's sister and one as Frank's mother. So I have merged the trees.
BUT - if I now ask Geni the relationship between Frank and Sophie, it STILL shows no blood relationship! Is this a bug, and how can it be overcome?
