This Johanna Wattmer seems to have been born after John Hatche "the Older" & Eleanor Hatche her supposed parents death.
In the reference I found this couple did not have a dau. Johanna listed. John Hatche "the Older" had a younger brother John Hatch "the Younger" who is listed with a dau. Johane but he died probably before 1536 and the dau. was born abt 1521. He also would of been deceased before Johanna Wattmer
I would suggest removing Johanna (Hatch) Wattmer as the dau. of John Hatche "the Older" & Eleanor Hatche
