Need to check the actual records. Charles has the occupation of laborer. I have no idea who Catherine is. My guess is that she was an aunt. No record of his brothers having married a Catherine.
More research is needed.
The census notes that Charles owns his home with no mortgage, he can read and write and was unemployed for 8 months this last year. They are noted as having been married 44 years with 7 children all still living. His occupation is listed as a farmer, he is an employer, they own the farm and have no mortgage. For a number of weeks he had been confined to his home with jaundice and his condition did not become serious until a few days before his demise. The deceased will be greatly missed from the community.
