Thomas Johson of Frederick, MD

I am interested in Thomas Johnson / Johnston Esquire of Frederick County MD.He was an officer in the Maryland Line unit, the German Batalion with oficers & neighbors Christian Lefever / Lefevre and Charles Baltzell / Balsel.David Lefever & Lefever heirs of Elias Lefevre Sr born 1743 sold in Frederick their land called Resurvey of Bennetts Resolution to Baker Johnson and "the Johnson brothers".
I understand that Lefever neighbor Thomas Johnson or his father married a Rogers. A nephew of Christian named Elias Lefever / Lefeber married a Catherine Craver in 1798 in Frederick and moved to Warren CO Ohio in 1806 or earlier. Their daughter Catherine born 1798-9 married a Robert or Richard Rogers in Turtlecreek Township, Warren Co., OH in 1817.I am looking for Catherine's grandmother, a Mary Salome wife of Elias Lefever SR. Her maiden name unknown.Maria Salome was born about 1748 or 1749.
