I'm checking into the possibility that your Mathias is the son of Mathias Parson - family settled in Lauramie Twp., Tippecanoe County, IN in the 1820s. Mathias had a son, Mathias, who may have received a land grant for property in Fountain Co, IN - I found a marriage record for Mathias Parson and Jemina Penwell, Fountain Co, IN, 12-19-1833.
Please feel free to email me.
