I misspoke myself slightly in my previous post: on the manifest, it states that the nearest relative of Janos (in Europe) is his mother, Maria Petra, who lives in in the village I mentioned. His birthplace was Szinna.
The other Janos Harkaly, who arrived in 1909 at the age of 41, was born in Csiroka-Hosszumezo, which was also his last residence. His next-of-kin in Europe was his mother, Mrs. Mihaly Polyak. He was going to his brother, Mihaly Harakaly, who was already in the U.S.
Looks like this same Janos made previous trips as well (in 1899, 1901, and 1907). Probably he is the father of the younger Janos.
