I received you e-mail today in regards to Joshua Kilburn and his son Timothy. I located the information that I sent to you through the book "History & Antiquity of the name and family of Kilbourne" by Payne Kenyon Kilburn, published in either 1850 or 1857. I don't know the exact date for I am having my book rebound for it was in poor shape.
I would like to correspond more with you if you could give me you e-mail address.
I have some information on a Timothy Kilburn born 4/2/1831 in Westminster Twp. Middlesex Co. Ontario, Canada amd died 4/21/1904. He was married to Roxanna "Annie" Reed. They had several children one who was a Timothy Bradford Kilbourn. I know this is not the Timothy you are searching for but we may be able to share more information about the Kilbourne family.
