Looking for information about Capt. Andrew Murdock (merchant mariner) born in Northern Ireland abt 1770 (+ or - 10 years). Married in New York City To Elizabeth Arcularius Shonnard in 1799 and died abt. 1812 at sea. Would like to find county of birth in Northern Ireland for Andrew. The city directory in NY City shows a Marshall Murdock ship capt. that I am sure was kin to Andrew. Maybe a brother. I think he died about 1803 or 1804 as he is no longer listed in the directory and Andrew is listed at the same address. The 1800 census shows both to be between 26 and 45 years. I have found Andrew listed in some dock records for New York. Any help will be gladly received.
