Vermont Gazeteer, Lamoille County:  "Sewell Newton, from Weathersfield, Vt., came to Johnson in 1800, and resided here until his death. Luther D., his only son, born in 1808, resided here until his death, in 1862, having reared a family of six children, only one of whom, Sewell, settled in this town." 

According to family legend, Luther had been to sea off the coast of Spain, came home and gave his two daughters these flowery Spanish names:  Kimetia Roena, and Isora Lavega.  No evidence has been found to prove or disprove this story, though a quick Google search reveals that Isora is an isolated town in the Canary Islands and that Villa Lavega is a rental house on Lanzarote in the Canary Islands.  La Vega is also a town in Dominican republic where Christopher Columbus searched for gold.  Additionally, it turns out that "Isora Lavega" was a not uncommon name for girls at that time.
