Hi, Mark -- Glad you found Benjamin's baptismal record. Sometimes I've found that tracking down siblings can lead to more information [Did they emigrate at the same time? What was their destination? Can I find their death information?] I hope you can find all of your relatives.
Gábor Ihász and his son were my grandfather's uncle and cousin. At the time of the Harwick mine explosion in 1904, the younger Gábor was only 17. He was listed among the fatalities as "Hungarian miner boy". My grandfather was 11 at that time and was already working in the coal mines near Barton, Ohio. They certainly had a hard life in this new world!
Stay safe!
