I'm researching a Frederick Horn THEAKSTON born in 1861 in London, England, emigrated to Nova Scotia, Canada circ 1864. At some point he made his way to USA, unsure of date and believe likely port of entry was Boston. Married a Mabel Adams in 1898 in New York, NY. He died in 1935 and buried with his wife in Wiscasset, Lincoln County, Maine. I'm trying to trace his life. In particular details about his immigration to the USA and details about his wife (I have nothing). Any help from those with US sources would be most appreciated. Images of gravestones (from findagrave.com) attached.
