Nancy Marie Griffis (Sheffield, and maiden name Johns) married Bruce A. Griffis in 2002. I thought perhaps Chad Griffis was an adult son of Bruce. But, I can't find any connection between Bruce and Chad.
What I did find was a 29-year-old Chad Griffis, related to Victor Griffis age 52 and his wife, Deborah Lynn Griffis, age 48, with a sister named Jill, age 25. Note that the Chad Griffis that Crystal Sheffield is engaged to (and is the father of her infant daughter) is 29-years-old.
Is there a relationship between Bruce A. Griffis and Victor Griffis? I'm wondering if they're brothers? That would mean that Crystal Sheffield (bio-mom) is engaged to her step-father's brother's son. There would be no blood relationship.
