I located several records that may help.
In 1895 census (Ancestry) I found George Lawson in Sandyston Township. Other family members were Jane, Oliver, and Vernie.
In 1885 census index (FamilySearch) I found George Lawson in Wantage Township. Other family members were Margaret J, Anna Mary, George O.
On FamilySearch I found a marriage index entry for George L. Lawson to Margaret Jane Ryerson 26 August 1878 in Sandyston.
In 1900 (Ancestry) I found Margaret Lawson, 38, widow in Sandyston Township. Her son George 18 and dau Melverna 13 were living with her. Melverna was born Jan. 1887.
On FamilySearch I found a death index entry for George Lawson in Sandyston Township. His death date was given as 9 March 1898. However, FamilySearch death dates for spring months are often wrong, it was probably 1899.
I think this is the family you are looking for. You may want to review the records I found and also get the marriage record for Verna Lawson and Elmer Crawn. That should give their parents' names.
