I am looking for a Silas Pollard, possibly of Shelby Co, KY. He married Prudence Sharp around 1830. They were in Gibson Co, IN in 1850. There is also a William Pollard (m Sarah Sharp 12 May 1825 Shelby Co, KY)in Gibson Co, IN in 1850. Are these two brothers who married sisters? Silas was born around 1814 in KY; Prudence b around 1813 in KY; William born around 1807 in KY; Sarah b around 1707 in KY. These years of birth are based on the ages given in the census. Thanks for any and all clues.
