Thank-you so very much for answering my request. According to Ancestry.Com census search, Matthias Parsons was listed in the 1850 & 1855 Census - in Utica twp, Winnebago co, Wis.The 1860 Federal census lists him in Winnebago co. also. I will check Ancestry.Com again for Iowa census possibilities.I think it is more likely Matthias & Jamine are buried without a marker somewhere in Winnebago co, but they might have moved elsewhere. It is interesting that Jacob Parsons and Lovina Whitman marriage record is listed in Winnebago Co!Family records have shown them married in Chickasaw Co., Iowa! Jacob Parson is buried at Richland twp cemetery near Nashua, Iowa next to his brother Joel Parson.The family dropped the "s" sometime around 1900. Again, thank-you for your help.
