areivimzehlazeh,
Do you have a basis for that? I think it is much worse to do bad in E”Y because it is compared to someone doing somehting in the palace of the King! (I read an article that E”Y can have an amazing effect on someone moving in the right direction but if he is on a downward slide to begin with then it would have the opposite effect.)
as far as names, I think Rivky Friedman is the most common combination for girls! For some reason Faigy Friedman seems to be quite common too even though Faigy is not as common a name.
I think Esty and Rivky are most common girl names and Moishy the most common for boys.
