Brother and sister coming to join other siblings?   Benjamin J's children Ida and Hyman?  Maybe that is why he went back to Europe - to get his children?  The dates do coincide....  If Ida was 17, she would have been born around  1893 and Hyman was 19 so he was born around 1890-91, which matches his gravestone.
