So am I :)
From what I know, Alfred Mattoon died 20 Apr 1854 and his grave is at Shelby-Oakland Cemetery...as is his wife's. She was born in Mar 1801 and died 12 Apr 1875. Some of this info is from the Richland County Obits page.
He had at least two sons. Horace B(igelow?) Mattoon and John G Mattoon. Horace Married Martha E Martin (daughter of William Martin of Pennsylvania) in Richland County in 1854. John G Mattoon married Sophia Richard.
If you are researching the Mattoon family, my particular interest lies with Horace B Mattoon's line. I have found only two children of H B Mattoon and Martha E Martin and both lived short lives.
Frank W Mattoon - 11 Nov 1856 to 26 Feb 1880
Lincoln Mattoon - 1 May 1860 to 19 Nov 1860
