Mare and Lesanne,
I spoke to one of the Maramarua Coxheads a day or so ago. Couple live in Thames, they know there is a family connection with the Manurewa family but that's about it. One of the earlier land owners at Maramarua/Mangatarata was George, (see Archway), that's why i got interested because The chap from WWI- DOD - was also George.
If by chance there's a photo of George WWI in the publications, I'd be interested.
