G2G: 1988 supplement lookup, Link Family

Question

I am hoping that someone who has the "1988 Supplement to The Link family, antecedents and descendants of John Jacob Link, 1417-1951" would be willing to do a lookup for me. I am searching for Rebecca Law who married John Linck on 29 Dec 1787 Rockbridge County, VA. Who is that John Linck descended from and where did they go after their marriage?

Thanks if you can help!
