It occurred to me that Samuel's cousin's name was more likely to be John Mahon, a common name in Ireland. So I looked for a John Mahon on Washington Ave. in 1920 and 1930. No luck. But in 1930, I found a John Mahon on 828 Classon Ave. in Brooklyn. In 1923, when Elizabeth was emigrated to New York to meet her brother-in-law Samuel Buick, his address was 669 Classon Ave. So this just might be Samuel's cousin John Mahon. John was age 46 in 1930, born Ireland, married at age 28, occupation caulker, wife was Nellie, age 39, born Ireland, married at age 21. So marriage abt 1912. No idea whether in Ireland or in Brooklyn. Might be onto something here.
