I am looking for any information regarding MARRIAGE RECORDS from around 1790, 1791 in the Cumberland, Maryland area for PRISCILLA SLAGLE & JOHN O’HARRA. A daughter of Jacob & Hannah Slagle, Priscilla’s family lived near the North Branch area of the Potomac River in Hampshire County, Virginia, & around Allegany County, Maryland. She & John O’Harra (possibly O’Harrow) supposedly married in Cumberland, Maryland around 1790. I’ve been looking for any information regarding her marriage, & also trying to find records regarding the birth of her oldest daughter Mary Polly O’Harra around 1791, born in Hampshire County, Virginia. I truly appreciate any help!
