You might try the PA Land records. http://www.phmc.state.pa.us/bah/dam/rg/di/r17-88WarrantRegis...
C160.104 in 1828 shows land owned by Denton Jacques in the Little Cove. This land was formerly owned by Andrew Dickerhoof who's buried a few miles south on the Licking Creek in Washington Co MD.
Foreman's book--History of the Little Cove might say something about the Jacques family also.
