Albany Co.Records, Court Minutes 1680-85,page 618.. Will 408, july 23,1683, 11 dec 1684.. Capt. Jane. refers to Nephew ( or cousin), Johannes Cloet,jun. then brothers, Jacob, Barent, Evert, Clement, sisters Annetje and Engel Cloet lived Nieuen Roy, District of the mark. He had no executers, the witnesses wer: Cornelis Van Dyck ( magistrate), Dirk Wessells ( ten Broeck) and Robert Livingstone, secretary. He also refers to Bata Slichtenhorst as Johannes wife ( The extracter erred in assuming this was his wife, but it was definitely Johannes wife)
I have always assumed that some one of his brothers or sisters named a child after Jan in the hopes of inheriting. Frederick seems to have come a bit later, but not much.
