did Dina gave birth of children from Shchem? how many kids did she have what names and what happen to them?

Shalom, Thank you for your question. According to the midrash, yes, Dina did have a child with Shechem. It was a girl, called Asenath. She seems to be the only child Dina gave birth to. The midrash states that this child was sent down to Egypt, and adopted by the family of Potiphar, and she later married Joseph.
