You are correct Jocelyn, I'm one of them, I floundered for a year, lot of the surnames were similar, but the tale was told when I tested my sibling. It took another year for my paternal sibling to fall in my AncestryDNA. Ancestry allows you to add another father, but anyone in MyHeritageDNA will see a tree that only represents only half of me & only will confuse my Jewish cousins.
