Aaron and Noah Stevenson appear in the 1871 census in Markham and in the 1881 Census with James G. Stephenson (name mis spelled) Noah appears in the 1861 census in Markham age 6, Aaron age 1 with their parents. After 1881 they disappear.
James G. Stephenson moved to Charlevoix Michigan and later settled in Elburn Illinois, but there does not appear to have Aaron and Noah with him.
They last lived in Agincourt but devout presbyterians they do not appear to be in Knox Cemetery Agincourt, they are not buried with their parents in St. Andrews Presbyterian Cemetery, Markham.
Anyone knowing/thinking they know where these two are please, please contact me.
