married Hannah Sanderson, their two sons my grandfather John Green and Douglas Raymond Green no dates for him only the fact he was a baker and their last known address was 142 Rutene Rd Gisborne, I had grown up in Gisborne i remeber going to my great grandmothers furnal and seen how big was plus i use to ring Douglas when i was very young. But not much said about my family history by my adopted parents. So now i would love to knw more about them and put them on my tree. Can anyone help me out.
