Hi: Union Deposit is in Dauphin Co., Hanover Twp. Check on net for a Dauphin Co Genealogy Society or directly to the Dauphin Co. county seat - better yet check your nearest LDS Family history center (library) - unbelievable depository of info usually for any state. Good Luck. Info came from book entitled "PA Line". Shows all counties, towns with populations, rivers, townships, etc. Wonderful book for resources. Sunny Seidel (originally from PA) Sonora, CA
