The best directions that I can give start with you on I-287. Get off at Exit 18, which is the one for US 202. Go north until you come to a traffic light; you will see the Dillon Library on your left, and a Texaco station across the road on the left. Turn right, and go about 1/2 mile until you see Peapack Road on your right (look for the fairgrounds). Turn left, and continue about 3/4 mile. You will cross the North Branch of the Raritan River. The next left is Old Dutch Road; turn there. After your turn, you will see a large white building across a field; this was part of the Moelich tanning operation. Continue up Old Dutch Road for a very short distance, and you will see a historical marker identifying the "Melick Home". It is owned by Mr. and Mrs. Perry Hall, and they are very welcoming to Melick pilgrims if they can conveniently do so.
To find the Moelich graves, retrace your steps and continue under I-287. On the right, you will see a cemetery; it has many Melick graves in it. Continue until you see an old-stylw white steepled church on the right, with a burial yard to your right as you face it. The Moelich graves are toward the back.
There are other Melick cemetery sites in Oldwick. Starting from the Dillon Library, you can continu a few miles into Oldwick; by turning right, you will come to the Melick Town Farm. Not too far from there is a cemetery with Melick graves; anyone in the area can provide directions. I do have a list of everyone in these cemeteries.
