No, I do not agree. Though it is a wild guess on my part I think the 'Van' would have been dropped by now, seeing that the rest of her siblings are all just 'Couwenhoven's. Also the remark that ' ... when the V from Van is combined with a first name, it should be wriiten with a lower case' is not the American convention. Quite the opposite. As far s I know it should be written with a capital 'V'. Any baptismal or other records if not destroyed by now should prove the LNAB. And if it is with a Van, then that should be the LNAB in her case. The rest of her siblings should be assessed individually.
