EATON
In 1919, they're on two electoral rolls :
1919 - Christchurch South General roll
EATON - John - bootmaker / Rebecca, married ... at 29 Antigua Street
1919 - Timaru Supplementary* roll
(* which suggests they'd recently moved to the locality )
EATON - John - bootmaker - Waimataitai
EATON - Rebecca - married - "Park View", Marchwiel Street.
[ ?? Separate addresses ?? I don't know whether "Park View" was perhaps an institution ? ]
