Milton Wright was a Bishop in the Church of the united Brethen in Christ and the father or Wilbur and Orville, see http://en.wikipedia.org/wiki/Milton_Wright_(bishop) as well as the page on the Wright brothers here http://en.wikipedia.org/wiki/Wright_brothers
On the first of those pages you will see that Lorin was the second son of Milton and so a brother of Wilbur and Orville. A page on him can be found here http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=6738910
Did the Wilbur H wright you are interested in have a life span of 1919 - 1944? See this page http://records.ancestry.com/Wilbur_H_Wright_records.ashx?pid=55005796 There you will find his ancestry back to past the time line for Milton. There appears not to be any link between the trees back as far as the 1700's.
