I may have information, if you are still interested. My grandfather, and frankly the family, loves discussing his crashing the water plane, again. There was a woman who sold furniture from the basement of the Derry Flee Market who has delightful stories. I'm afraid a fire and a decade has lost her information. I pray for bits you might know. I am told that although his latter days were dementiated, he was surrounded by love. Regarding the family: look to Tiverton RI.
