_Van Barr._ _Van_, Dutch for son, doubtless from Irish _bean_, woman;
_barr_, summit, top. Son of Barr; son of a man of eminence.
_Vannaman._ _Van-na-mann_, from _van_, son; _na_, of the; _mann_, man.
Son of the man. Names commencing with _van_ are considered by writers of
philology as Dutch, but in many such terms the student readily perceives
an Irish origin. _Van_, without doubt, is nothing but _bean_, the Irish
for woman, with its initial consonant aspirated.
