[note the typo in conjux; ouch to skip a letter in such a permanent medium]
To the memory of my most beloved wife Christine (?) / Christiana, whom, released by death in the 48th year of her life (up to the 48th year of her life) (March 27 (yes?), 1816), her grieving husband, George W. Chapman, a doctor, venerates with this marble inscription and attests to her virtues. May she rest in peace.
