As a young girl (I'm now 40) I babysat for a really nice lady, I remember her having a friend by this name, she came from Wellington & moved to Masterton in the 70's, I'm thinking she was a friend & not related to her. I don't remember her being married, I lost contact her this lady so I'll ask my mum tomorrow & see if she know's.
It looks like the parents lived in 23 Rona St, Wellington for a long time, I looked up this property to see if the PIKE name is mentioned in the past.
There is the Emily Elizabeth PIKE mentioned, but surprisingly there is a mention of another surname & it's the same as the lady I babysat. So now I'm thinking maybe they were related in someway... I'll see if I can find out over the weekend.
