I am looking for a Berrier(Borger) family that lived in Mercer Co. in the period 1820 to 1850. John Berrier (Borger) was born in Poland and came to the US. He married Ann Ferguson and they had a family of several sons in Mercer Co. The last name may have been listed as Berrier or Borger, or possibly other variations. My great grandfather was Matthew Wilson Berrier, born in Mercer Co. in 1835, if my information is correct. He married Isobel Franklin, the daughter of William Franklin and Elizabeth McNutt. If anyone has information on these people, I would appreciate it. This is so far a dead end for me.
