When Catharine Egbert was born in 1772, in Richmond, Richmond, New York, United States, her father, Abraham Egbert, was 36 and her mother, Elizabeth Van Cleve, was 24. She married John DuBois about 1793. They were the parents of at least 4 sons. She died in 1851, at the age of 79.
North German: from the personal name Egbert, composed of the ancient Germanic elements agi(l) ‘point, edge (of a sword)’ + berht ‘bright, famous’.
English (Devon): from the Middle English personal name Egbert (Old English Ecgbeorht, from ecg ‘sword’ + beorht ‘bright’). The present name in Britain usually appears to be of ancient Germanic origin (see 1 above), cognate with the English one, as the medieval name may not have survived.
