Seeking Edward R Butler from Martha S Vineyard Came to Hawaii 1813

E R Butler was living in Lahaina, Maui in 1820 when first New England missionaries
arrived...he provided them with lodging, food, etc...he is said to have been married
to a 'part-native' girl by whom he had 3 children. Do not know when he departed
Hawaii or when, where he died...or, anything re his children. He 'owned' land on
Maui and Oahu which he said King Kamehameha I had given him....
