I found three listings for "Gregory Wiggins" in California. One is 34 years old, one is 42, and one is 52. Middle names are included in the listings. On the basis of age, perhaps you can figure out which of these, if any, is the one you're searching for.

Contact info for all three is available at this site for a very nominal fee (under ten dollars).
It's worth a try...
Best wishes, Sharon
