Beardsley Hanchett Information

I am researching James Harvey Beardsley and Sarah Hanchett. I need proof of the following:
James Harvey -birth 29 Sep 1798 in NY state, marriage about 1820 probably in Lorain County Ohio, and his death 1851 in Dover, Cuyahoga, OH in 1851. For Sarah I need proof of birth 1798 in Pleasantville, Westchester, NY and death in Amhearst, Lorain, OH about 1834.
Any help will be greatly appreciated.
