You didn't say wen he died but I suggest trying to get his obituary. You might get lucky as it may not give his parents' names but might have where he was born.
In case you don't have it, he is listed in the 1850 census of Wayne County, OH under the name of Neisley. Living with them is Martha Reinheart 10. Everyone in the family was born in OH. He again is listed as a potter.
