I am your second cousin!
Your grandparents Eric and Ellen were definitely from England (London) and Eric was my Dad's brother (my fathers name was Ron).
Their childrens names were Christine, Paul. Barry, Graham and Ross.
Not sure where they are now but if you contacted HAROLD meecham in Rotorua (Erics younger brother) he could probably tell you. There are lots of Meechams in Rotorua darl.
