Here is a start.I went on the internet to Ancestry.com and typed in "Ambrose Knox".Found that he married a Polly Read in Montgomery Co. KY 12 Jan 1834.From that I looked up the 1850 census (I have access to the KY census).
1850 Bath Co. KY (right next to Montgomery Co.) 1st district 20 Aug. 1850
Ambrose Knox, 41, shoemaker --all members of the family born KY Mary, 41 Armelda, 13 Caroline, 12 John C., 10 William T, 7 Elizabeth 5 Z. T. Winfield (sp?) 2 Mary F.11/12
I hope this gives you a start.Genealogy is a wonderful hobby.
