I searched my charts.I found a Mary Allcock bc 1846 married an un unk Rogers.She was listed as the daughter of Benjamin B Allcock b Dec 1812 Graves Co, KY& Elizabeth Jane Harrison b 18 Feb 1820 KY. I show one sister Elizabeth Allcock bc1848. I have no more details, in my charts, on this family group at present time.
If this is the family you are inquiring about, Benjamin was the brother of my Thomas M. Allock and they were the sons of Durand/Durin H. Allcock 1787-1844.Yes, Thomas had a daughter Ann.
I have not worked on this line in a long time.Guess it is time to get back into it!:-)
