Wouldnt say i was happy,but Roberts date of birth has varied from 1809/10/12/14 and 16.
Im quite sure if i was sailing to another country for a better life i would remember the name of the ship, its not as if the Solon and Erin are similar. So on that basis im goin to go with the written evidence, he was on the Solon.
I do have another entry for the savings bank and that states 1837 as a date of entry, so contradictions all round, but your right things could have been mis heard.
I'm told the area my ancestor came from in Ireland has one of the most 'strong irish' accents there is and even others from different parts of Ireland have difficulty understanding them, so it would be possible.
I'll keep searching for the Solon i think and maybe check dates from 1837 to 1839
