The name Montgomery is from my side of the family and dates back to Major John Montgomery born in 1670. Major Montgomery's grandson, John, immigrated from Ulster to America in 1720 and married Esther Houston. They settled in Augusta County, Virginia. Their daughter, Dorcus Montgomery, married John Edmondson Lowry. Dorcus was my great-great-great- grandmother.
The name Montgomery dates back to Norman times. The clan name first appeared in Scotland in the 12th Century.
