Searching for the maiden name of Margaret Haddock, I came across some detail about a marriage entered on Richard Haddock's findagrave entry stating he was "Married to Margaret Boteler about 1525. Daughter of Sir Robert Boteler 1459–1514 and Lady Dorothy of Stowmarket Le Boteler Tyrell 1459–1491."

Even though the location, time and relations seem reasonable on there own, I continued to look for the Boteler connection through familysearch records. This lead to another findagrave entry for what may be the parents of Margaret Haddock; Margaret Belknap 1472-1513 (L6FJ-W6W) and John Butler 1459-1514 (LRDB-KKK)
