Here's Owen Grant's arrival through Ellis Island in 1914
https://familysearch.org/pal:/MM9.1.1/JJ7M-PNTThe scan of the original document on the Ellis Island site shows that Owen travelled with 4 others from Stranaclea, Illies - Charles O'Connor (30), brothers Andrew (30) and Michael McLaughlin (27) and Michael Kelly (27). They all gave their next address as Mrs. Mary Mackon, 110 E. Wilmott St. Butte, MT.
It appears that Andrew McLaughlin had previously lived in the US and was now returning with the other 4 individuals. He listed himself as "Returning brother" which implies that Mary Mackon was his sister.
In reply to the question who he was going to stay with - friend / family and address, Owen Grant 's answer was "(friend) brother Patrick Grant" at the same E. Wilmott St. address.
And here would appear to be the draft registration card for Patrick Grant in Butte City, MT
