Archibald Mossman prob. was the orphaned son of Hugh and Cecelia (Bertram) Mosman of Edinburgh. Proof is difficult. Their fourth son Archibald was born ca. 1768, a date consistent with Va. records. Archibald was the third in service of heirs to his uncle John Mosman (Scottish Record Office Vol. 24, Folio 224, No. 803). Perhaps differences of opinion come from uncertainty about those who actially raised him.
