Craig's "The 1693 Census of the Swedes on The Delaware": Craig's text indicates that Corn. Vander Veer's wife's parents were "unknown".
On pg 147 with regard to Anders Sinnicksson, he flatly states that Margareta, dau of Måns Pålsson was Anders first wife...married by 1678. He states that Anders was sued for medicines supplied to his wife and child. Anders was survived by his second wife Sarah and seven children: Ingrid and John by his first wife, Anders,Margaret, Sinnick, Catharina and Dorothea by his second wife.
Craig further states that biographies written about Anders Sinnicksson are fictitious and totally unreliable including that by Thomas Shourds, 1876.
Most of his records for the above are from New Castle Court records,(NCR), 1:34, papers of William Penn, (PWP)and Salem County Wills.
He further mentions, pg 117 that altho Måns Pålsson's, (in the will),other children, Paul and Margareta had been provided for, Margareta was to receive an additional 35 guilders. Source: Johnson, 517-18, Rising, 211 and more.
