Bojay on Family Tree Circles

Hi All, Trying to trace the above person, my great grandfather (paternal) who emmigrated to NZ from Glasgow aboard the ship VIOLA, landed at Auckland in April 1865. . At that point of
time we lose track of him. He then turns up in the Victorian goldfields in Bendigo, not sure when or how. We believe he ran a butcher business, and had a son James Charles/Clarence Owen who later worked in Bendigo as a blacksmith and possibly also as a miner. James Jnr, later left for NZ and in 1919 married my Grandmother Florence Ada Proctor. Looking to trace my Great Grandfathers roots. Any information regarding this relative would be greatly appreciated. Thanks in advance, Bojay
