I'm looking for resources to research an ancestor's reported death at sea. John H. McCarthy was a seaman in the period 1870-1889. He lived in the NYC area--Brooklyn and Staten Island. According to family lore, corroborated by his son's passport application, he was lost at sea circa 1889. I have not been successful in locating any record of his death in NYC archives, nor in contemporaneous newspapers.
Any thoughts on where to research a death at sea in 1889 greatly appreciated.
