NEW INFORMATION ON THE ROSIER FAMILY
Lawrence Rosier January 10, 2000
The Mother of John Rosier (1781 or 1785, PA -15 Sept 1867 Parkton Md) was probably Elizabeth Rosier who was living in 1798 on the property which became John Rosier's. Their father and other family members are unknown. However John is thought to be the uncle of Abijah Rosier who moved next door between 1850 and 1860.
