Looking at census data for Levi it shows him as 40 in 1841 [appreciate the rounding down factor] and then 53 on the 1851 census. From his death cert [I have a copy] it shows him dying 27.07.1872 in Brind aged 74 which gives a birth year of 1798, as for place of birth I don't actually know. As you mentioned all these villages are close together ie walking distance, therefore I would dismiss Leonard b1799 in Dent as too far away.
Levi married Ellen Penrose [some people have her as Pearson] 1st Jan 1828 in Howden.
I have had a trawl through the familysearch.org site [didn't realise you could do it that way] and have confirmed with my data the following:
Levi was born to Thomas & Susannah [Hamson or Hampson] he was christened 09.08.1801 in Howden. He had 9 other brothers & sisters:
Ann 1781, Mary 1784, John 1786, Elizabeth 1787, Harriet [or Harriot] 1790, Jane 1793, William 1794, Thomas 1794 [a twin of William?], James 1796.
I have Thomas [father of Levi] b 1751 to Thomas b1733 & Mary Illinger [married 09.04.1751]. Thomas & Mary had another son James, I have nothing for him.
The level above this shows Thomas b1733 to Thomas [b1707] & Ann Throstle [1710-1750]
I am happy with most of the data I have ie upto Levi, it is before him that it gets a little confusing - mainly due to Thomas being a very common christian name.
