Arthur James Abbott married Coraline Elsie Maud Neilson in 1907.
I found an Arthur Abbott arriving in New Zealand aged 5 in 1874 with his parents and six siblings. This could be him. His father (Henry) is listed as a Navvy from Warwick in England. A Navvy is someone who builds railways. If this turns out to be your gg grandfather, I can send the ship's immigration log if you want it.
