Looking for some conundrum breakers assistance. One of the men my biological mother married used an alias (see Moran-4022), I was able to sort him out a bit, however, his father (Moran-4704) has stumped me. I've found a marriage certificate and one census record. There is a possibility he worked on a ship as part of the crew, based on some research documents that came up. I don't know how to prove or disprove this. His employment on a ship would explain his wife citing herself as married in following census records, yet no husband accounted for in the household. Any assistance/guidance/suggestions would be greatly appreciated.
