Karen I think I found your Reason Leak in Ohio.  Would be in Warren Township, Tuscarawas Co., Ohio.  Page 88 1830 Census.  One male (20-30) and 1 female (15-20).  Fits and doesn't belong to my Rezin as I thot he might.  Traced my Rezin back to his marriage and he didn't have a boy this age.  Hope this helps.  I haven't looked to see where Clarksville is, but they must have been married by 1830 so probably a couple of older kids out there. Please let me know if you have found more as I am continuing my search to tie all these Leak/Leek families together. Jerilyn
