You may mean Lewis Milton (b. NB ca. 1818) with a wife, ‘Emme’ (b. NB ca. 1826) with children, John A. (ca. 1848) and William H. (ca. 1850), living in Harvey Parish, Albert Co., NB in the 1851 census. The area also brings to mind the surname, Mitton, sometimes given or transcribed as Milton. They are actually transcribed at:http://automatedgenealogy.com/censusnb51/View.jsp?id=1021&am...
Assuming the surname was Milton, one clue may be that Jane b. Hopewell Parish, Albert Co., NB ca. 1808 was the daughter of Henry and Rhoda (Wickwire) Milton. She married 28APR1825 William G. Martin. Jane had an older brother, John Milton (b. NS ca. 1783, d. 8JAN1860) who m. 5JUL1808 Margaret Steeves (Stiefs) Milton (ca. 1787-29JUL1827), d/o Lewis and Elizabeth (Porter) Steeves. Perhaps Lewis Milton was one of their nine children. The only one of those children who seems to be known was Peter Milton (ca. 1807). Peter is also in Albert Co. in 1851 at:http://automatedgenealogy.com/censusnb51/View.jsp?id=1139&am...
The Milton family, in 1851, in Albert Co., was relatively huge. There is more at:http://freepages.rootsweb.com/~coleharbour/genealogy/Milton/...
Henry Milton b. ca. 1760, m. Cornwallis, Kings Co., NS 2MAY1781 (11MAY1785?) Rhoda Wickwire (b. Cornwallis, Kings Co., NS 18JUN1762), d/o Peter and Rhoda (Schofield) Wickwire. This suggests New England Planters who settled in Nova Scotia after the Seven Years War (1755-1763).
At the above website, Lewis Milton is given as the s/o John Murphy Milton who m. Margaret Steeves, d/o Ludovic (Lewis) and Elizabeth (Porter) Steeves. If the Milton family is relatively huge, the Stief family is enormous. Lewis had a son, Reuben, b. ca. 1852.
The 1861 census of Alma Parish, Albert Co., NB seems to be missing but the Library and Archives Canada site has a partial transcription in a typescript that includes on page 10 of the original, Lewis Mellon or Melton with a wife, Amy, and children, John A., William, Isaac, Reuben, Lewis, Anna?, Ward and Mariner. See:http://data2.collectionscanada.gc.ca/1861/jpg/4108532_00010....
In Alma Parish, in 1871, Lewis Milton (53) and Mary Jane (40) Milton had ‘Ruben’ 18), Lewis (16), Abner (14), Ward (12), David (8), Mariner (7) and Eliza (8). Mary Jane (b. Ireland) appears to be a 2nd wife. Anna? becomes Abner. Where was David in 1861? See:http://data2.collectionscanada.ca/1871/jpg/4396319_00612.jpg
In Alma Parish, in 1881, Lewis Milton (24) is a ‘Sea Captn’. With him, as well as his wife, Eliza (19) are his siblings, ‘Rubin’ (27), Abner (24), David (18), ‘Mernar?’ (14 and their stepmother (?) Mary J. (52).http://data2.collectionscanada.gc.ca/e/e325/e008124942.jpg
By 1910, Reuben Milton (b. Canada ca. 1856) is in Portland, Cumberland Co., Maine. In 1920, ‘Ruben’ Milton (b. Canada ca. 1853) is in Westbrook, Cumberland Co., ME.
Lewis’s 1st wife is given as Amy Martin d. Albert Co., N 27MAR1866. Possibly a d/o Thomas (ca. 1801) and 'Molvina' (ca. 1804) Martin of Harvey Parish in 1851. More likely she was a d/o William (ca. 1803) and Jane (ca. 1806) Martin. The Martin's are particularly numerous in 1851 as well. William's wife, Jane, was Jane Milton, Lewis Milton's aunt. Molvina Chapman was Thomas' 2nd wife. He was William's brother and they were sons of James and Prudence (Wickwire) Martin where Prudence was a d/o Peter and Rhoda (Schofield) Wickwire.
Reuben Milton d. 7MAY1927 and is buried in Woodlawn Cemetery, Westbrook Co., ME. David S. Milton (1863-11FEB1807) is also buried there. Probably Lewis Milton (d. 7NOV1946) was related.
This stuff is hazy and needs work, but might give a start.
