You can find information on Joe Link who md a Knoll and were from Defiance Co, at my web site www.barbergenealogy.com
and go to the record section and then find the Knoll family and there you will find the Link families. I was raised near the Link farm which was on Shindler Rd. Spent many of summers in the woods there playing cowboys and indians with all the neighboor kids. I have the Link family book written by a Link in CA. Good luck and email me if you need additional information.
