Hunterdon County New Jersey Queries

HARTRUM/PARKS/LOTT/HAZLETT
Daniel HARTRUM was born in Clinton (1850's?). Sarah PARKS was born in Flemington on 1/21/1855 (d.8/20/36). They were married in 1875.
I have almost no information on James LOTT or Elizabeth HAZLETT except that they were the parents of Bertha Lott who was born in Hampton 9/23/1893.
Any information on the ancestors of any of the above would be appreciated.
Thanks,

Ron Hazelton
