I have managed to trace my lineage as follows :
Valentine Kaub-Susannah (PA)
Frederick Kaup-Mary Rice (PA>OH)
John Coup - Esther Springer (PA>OH)
Joseph Coup - Rebecca Noecker (OH>KS>OK>?)
Wilbert Coup - Alice Elizabeth Robinson (NZ)
George Wilbert Joseph Coup - Jean Rhoda Mitchell (NZ)
Daryl Bruce Coup (NZ)

I have found many siblings for each generation and am now trying to fill in some of the details of colateral lines, and perhaps locate some long lost relatives. Wilbert lost contact with his family about the mid 1920s. If anyone is definitely linked then contact me at daryl.coup@stonebow.otago.ac.nz
If not I would still be interested in anything you may have on Kaub-Kaup-Koup-Coup. I am trying to piece together all the different lineages.
