James Livingstone emigrated from Glasgow region c 1872. Travelled to America, where when arrived, what ship?

James Livingstone would have been aged abt 44 when he left Scotland for America. Thought to have worked at Goldhill, Nevada before going to Rock Creek, Otoe, Nebraska where he bought land and Married Euphemia, born in Canada to Scottish parents. They had several children. James is shown in American Census as being 73 in 1900. Then there is an enigmatic entry that states that he had died in 1901, and his spouse?, Grace Ballantyne was deceased. Problem is, Grace Ballantyne is known to have died in Scotland in 1901 and James Livingstone (the same man?) died six months later. Are the records stating that James sailed back to Scotland aged 73 leaving his American wife Euphemia behind. Perhaps Euphemia was trying to get a pension from the American Government and the Government needed James' death confirmation. Perhaps there are shipping lists for the late 1900's early 1901 from America to the UK showing that James did actually sail. Perhaps there are descendants in America know real story?
