My grandfather was Henry Thomas Cunniff b. 1910 of South Boston. He was the son of Henry Thomas Cunniff, Sr. b. 1887 of South Boston. My father was Henry Thomas Cunniff, III born 1944. I know that Henry Thomas Jr. has siblings, James, Robert, Mary, and "Sis", although I do not have detail on marriages, etc. I too remember the name Mary Scannell growing up. And, also recall hearing of Roland or "Rolly". I do have more detail on HTC, Sr. and his parents/grandparents,if this is the same family branch . . . and would be interested in any further information you may have.
