There were/are at least 3 Kitchen families in Norfolk. I do not know if they are related but some you will find today in Haldimand, Brant, Oxford, Elgin and Wentworth counties. They pop up from time to time in the Obit's of the Simcoe Reformer, one just last week who lived in Elmira which is in Waterloo County. I see Dorothy daughter of Clendon and Etta died in 2005 in her 100th year her obit is in the Brantford Expositor.
If you have Ancestry there are message boards. Find Norfolk search Kitchen there are pages of them. Do same for Brant, Oxford and Elgin counties. You should find some more pieces.
