Name Meaning for "Allen"
English and Scottish: from a Celtic personal name of great
antiquity and obscurity. In England the personal name is now usually
spelled 
Alan, the surname 
Allen; in Scotland the surname
is more often 
Allan. Various suggestions have been put forward
regarding its origin; the most plausible is that it originally meant
‘little rock’. Compare Gaelic 
ailín, diminutive of
ail ‘rock’. The present-day frequency of the surname Allen in
England and Ireland is partly accounted for by the popularity of the
personal name among Breton followers of William the Conqueror, by whom
it was imported first to Britain and then to Ireland. St. Alan(us) was
a 5th-century bishop of Quimper, who was a cult figure in medieval
Brittany. Another St. Al(l)an was a Cornish or Breton saint of the 6th
century, to whom a church in Cornwall is dedicated.

Their daughter married Dimick Huntington :
Here is the biography I have for Dimick.  Though I don't see evidence of
 a third wife, I do see a reference to a squaw.  See below:
DIMICK BAKER HUNTINGTON, born May 26, 1808, in Watertown, N. Y.; married
 in 1830, in Watertown, N. Y., Fanny Maria, daughter of Gen. Clark 
Allen, (descendant of Ethan Allen) and Martha (Thompson) Allen. She was 
born October 26, 1810, in Loraine, N. Y., and died December 14, 1894, in
 Pleasant Green, Utah. She accompanied her husband in the famous Mormon 
Battalion march through the deserts, enduring all the hardships of a 
soldier's life. She was for four months without tasting bread, before 
her daughter Betsy Presendia was born, living on roots. When the girl 
was born at Pueblo, on Mexican Territory, she had no mid-wife or doctor,
 so an Indian squaw attended her. He married a second wife, about 1853, 
in Salt Lake City, Ellen Sophia Jacobson. She was born in Norway, about 
1826, and died in Parowan, Utah, about 1900.
He was Indian interpreter for the U. S. Government up to the time of his
 death, which occurred February 1, 1879, in Salt Lake City. He was a 
private in Co. D of the Mormon Battalion, and as such took part in the 
Mexican War in 1846. He enlisted July 16, 1846, and was discharged July 
16, 1847. He was a member of the Salt Lake City Council in the early 
days. He was High Priest in the Church of Jesus Christ of Latter Day 
Saints. He was instrumental in helping to settle and colonize the whole 
region south of Salt Lake City, down to St. George on the South border 
of the Territory. He acted as interpreter for the Indians, as a soldier 
of the Mormon Battalion, and he helped to secure
California, Nevada, and Utah, for the U. S. He published three books for the benefit of the Snakes and Utes, (Indians.)
