I have seen references to both the Mercer Co. Genealogical Soc. and the Mercer Co. Historical Soc. I don't want to offend anyone, but how do these two organizations differ? (I am told that the Gen. Soc. is open only on Tues. and Thurs. and that the Hist. Soc. is open Tues.-Sat.) Are they both located in Mercer? Does it help to belong to both? Gretchen
