I have looked at wht you have sent and sorry but I have nothing to add.
However over the winter months I will be going through my boxes(all 10 of them) and adding information which I documented some 30 years ago at the Cannington township Office.(Births , deaths, marriages, and also cemetery transcriipts for the area)
I will save this information and if I come across anything I will send it to you.
I have a feeling that my connection to the Cowan family will be through my Edwards side.
Good luck
