I am looking for information about my wife's farfar, Anton Bengtsson, aka Anthony Bennett or Anton Bennettson. He was a Swedish seaman who jumped ship in New York City in about 1880. We have checked all available sources within the USA for information about him, without much success. He was not recorded on any USA census until 1920, his marriage certificate cannot be found, only the birth certificates of two of his eight children and his death certificate have been found and they only give his place of birth as Sweden.
Is there a register of Swedish seamen where he may have been recorded and where his jumping ship in New York may be recorded? This would seem to be my only hope in finding the right Anton Bengtsson. His death certificate says he died in New York on May 9th, 1910 at the age of 49. This would have made his birth date about 1861. But on the birth certificate of one son, born in 1888, it gives the father's age as 32 and this would make his birth date 1856.
I would deeply appreciate any assistance or advise you can give me.
