There is a paragraph on the Frederick Alberty family on page 2 of "Arkansas Pension Applications 1818-1900" compiled by Dorothy Payne, 1985. He filed for a Revolutionary War pension in 1819. His wife Elizabeth Rafer is mentioned also. There is another paragraph on John Alberty who married a Cherokee woman Mary Wright and this family ended up in Washington County AR. My Lewis family has some connections to this one. Hope this helps.
