Rebekahm you ask Casalguidi about biblical names such as Abraham and Moses, I hope you will excuse me for jumping in. Baptists, Methodists, Catholic, Lutheran etc., all Christian faiths in fact would use the bible and be familiar with those names even when they couldn't read because they would listen to sermons and bible readings by priests and other church leaders and hear names like Aaron, Adam, Deborah, Rebecca, Sarah, Samuel & Samson etc. The Jews used the names from the Old Testament too of course.
In my family the Goldsmiths who I thought might be Jewish turned out to be Primitive or Particular Baptists and they used names like Moses and Aaron from the Old Testament and Thomas from the New.
I hope this is helpful to you,
