Alexander and Rebecca were married by Cotton Mather.

The charms of tbis beautiful Miss Shattuck, whom he met in Boston, enamored the nobleman, and Mr. Sampson (for that was his name) was captivated, and the nobleman never returned to England. A grand wedding seemed to consummate their earthly bliss. Mr. Sampson was very wealthy, having large interests in the London docks, where the immense amount of shipping made an investment in these docks immensely valuable. While on a pleasure excursion one day on Boston Bay, his boat was capsized, and Mr. Sampson met a most horrible fate; being devoured by voracious sharks. This most shocking catastrophy almost killed his beautiful wife.

This man's fortune was said to be very large, but inaccessible, especially to outsiders, as it could only be reached and obtained by a long, tedious and expensive course of law, through the English courts of chancery. One of the heirs in this country, a Mr. Sampson, of Cincinnati, went to England to make enquiry and investigate, and learned that the estate had been appropriated by the British parliament to the London dock company, and the money put into the bank of England in different installment; that the amount was large and had lain there drawing interest for more than forty years, but could not be obtained unless the heirs could legally trace their ancestry, and establish their exact connection with the last possessors of the property. He found the fortune so hedged in, and requiring so much time and money to get at it, that he gave it up.
