The Kent and DeVold Family Tree

I am searching for decendants of James Henry Kent who was born on November 28, 1975 in Turo-Sub-District-Kea Cornwall England, he married Mildred Kendall who was born on April 8, 1888 in Redruth County of Falmouth Rd. England. They came to the United States, but I don't know when, or any details. For example, if all sisters and brothers came with them, if they got married in England or here in the U.S. Family rumor has it that they came with family members one that didn't come to the U.S. was a sister named Clara, it has been said that she went to Africa and was never heard from.I would like to learn about James' parents who were William Henry Kent and Elizabeth Ann Evans and Mildreds' parents who were Frederick Kendall and Elizabeth Couch both from England..Other family members that I am searching for is Olas DeVold who was born in 1845 in Tronjiem, Norway and his wife Martina Wilhemina Davidson who was born in 1848 also in Tronjiem, Norway. Here also I don't know if they got married here or in Norway.Any information regarding parents of Antoine Dobbs (1854-1946) and Julia Amell (1860-1946) would also be of great interest.This has been an interesting project, I can see why people continue to research! If you can provide any information it would be greatly appreciated!
