Since Isaac is described in his father Abraham's 1738 will as "now a single man" and since Abraham leaves him "only £50 for reasons known to myself," I am led to believe that Isaac may have divorced a first wife against the will of the family. Isaac would not be entitled to any inheritance, except for the £30 year from his brothers-in-law, unless he remarried. -Judith

In 1738 (age 30) (the year of his father's death) Isaac, hoping to profit from Caribbean trade, set sail for the West Indies. According to the Jewish Encyclopedia, Isaac came to the U.S. via Barbados, settling in NY. During the Revolution, the Seixas clan fled from the British in NY (1776) and settled in Stratford, CT. Isaac later moved to Newport, RI.

Caused an uproar in New York's Sephardic elite by marring an Askenazi Jew. See Leo Hershkowitz & Isidore S. Meyer, eds., Letters of the Franks Family (1733-1748): The Lee Max Friedman Collection of American Jewish Colonial Correspondence (Waltham, Mass.: American Jewish Historical Soc.), pp. 75-76.

Issac did not invite any of his relatives to the wedding and his Uncle Rodrigo Pacheco (Benjamin Mendes) was "displeased" according to abigail Levy Franks in a letter to her son Naphtali, half sister to Rachel.
