Welcome to RootsChat Eric.
Thanks for sifting those names from the mix and the added information, helpful to me and no doubt others searching the Cook name as well.
I was sidestepping the direct line of my own search there into another branch, just looking for possible links.
When I discussed some of this search with elderly aunt at the time, she seemed to think name changed in her line from Cook to Cooke when her grandparents were in Taranaki to avoid some mix up but couldn't clarify and of course both relatively common anyway.
