Following up on Obadiah Mendes Da Costa. Many sources indicate that he died April 1848 and that his wife Eliza, nee Mendes Da Costa, survived until 1897.
However I have just found in an online version of the Occident and American Jewish Advocate, Vol. VI, No. 6, Elul 5608, September 1848 the following obituary:
Died, at the island of Curaçoa, on the 10th of June, Mrs. Eliza Brandon Da Costa, wife of Mr. O. M. Da Costa, of the above island, and daughter of Mr. Jacob De Fonseca Brandon, of Hackney, near London, England. Mrs. Da Costa was born on the 28th of February, 1804, and was married in New York at the house of her brother, Mr. Joseph Brandon, on the 25th of December, 1833. She died much regretted by a large circle of friends whom her kindness of heart had gained her, leaving an only daughter, thirteen years old. May her bereaved husband and child meet with the consolation from above which their loss demands.
This suggests that Obadiah was still alive in June of 1848 at least. Can anyone clarify?
I'm also wondering if anyone knows to which branch of the Mendes Da Costa family Obadiah belonged.
