Father-in-law hit a wall here. Mary Catherine DeGroft 1842-1917 md Isiah A.Kreglo 1840-1915. One dau, Flora Catherine 1874-1960 md Edward Kenney 1877-1939. Another dau, Elsie was raped & murdered when ~15 yrs old, the man who did this was hanged. She is buried in church cemetery just off Allentown Rd, approx 1/4 mile fm MD 5/Branch Ave, adjacent to Andrews AFB MD. Probably other children which I do not have. They lived in Prince Georges Co MD. Any connection would be terrific. Thanks.
