1. I see the people with surname Ben Aharon ... in the individual list under letter B. The wife is printed under Aharon. Same for Ben-Davis and David.
2. I have father with surname "Ben Aharon" or "Bar Josef". When I add a child or a parent, they are added with surname Aharon or Josef and surname prefix Ben or Bar.
1 NAME /Ben Amitay/
2 SURN Ben Amitay

I do not see the Hebrew name on the English close relatives tab, on the family page, the family list or charts.
On the Hebrew pages I see both names.
