No, I'm so sorry,
Dee. I wish I could say yes.
You are a
Wrenn. If you married a
Smith, your boy children will carry the
Smith Y-chromosome. If your daughter married a
Jones, her boy children will carry the
Jones Y-chromosome.
This is how I came to understand it: when a child is conceived, the mother can only contribute an X-chromosome. The father, however, can contribute either an X-chromosome or a Y-chromosome. In so doing he determines the sex of the baby.
If Dad contributes an X-chromosome, the child becomes a girl. If Dad contributes a Y-chromosome, the child becomes a boy. Two Xs make a girl, but one X plus one Y make a boy.
So every male on this planet carries a Y-chromosome passed down from father to son for generations. There might be a mutation here or there as the years go by, but the y-chromosome can be recognized and compared with other descendants, making it very handy for genealogical research on surnames, which are also passed from father to son.
Your best bet is to find a related male carrying the
Wrenn surname and talk him into taking a test.

P.S. I am so sorry about the wild child --- I don't know who suffers the most in such situations: the child living the dangerous life or the loved ones who worry about him.
