The name is of MUSTON, not Munston and it's very easily checked anywhere. There is no such a thing as Churchill of Munston.

From Re: Churchill-Bogart Connection 2005

John Churchill, the eldest son of William, was born about 1512.Note that your birth date of 1561 would have him born when his mother, Mary Creuse, was about 71, as she was born about 1490.John married Edith Bond.He died between 15 April 1557 and 25 August 1557.He had three children, William, Elizabeth, and John. Younger son John had two daughters, Anne and Elizabeth. William, born in 1541, married Missy Swayne and had six children, the first two of whom were sons, William and John.

ancestry

Thomas and Grace (Tylle) Churchill had sons Thomas and William. Thomas was the eldest. He married Ibote [true spelling Iseult] Provedher and in accordance with the custom of the day assumed the whole of the Rockbeare holding upon the death of his father (i.e. through Primogeniture).

William was married off to Mary Creuse the eldest daughter of Richard of Wicroft (Wycroft) Castle in Devonshire. He initially removed to Colyton, Devon (pronounced like “Colliton.”) where he apparently became a minor Copyholder (a renter). He then removed to Catherston Leweston in Dorset where he acquired free tenure (possibly through Richard Creuse or possibly in his own right since he was a Yeoman of Devon). He is the earliest confirmed ancestor of the Dorset Churchills and was the progenitor of the later very prominent Churchills of Colliton and Alderholt Park.

His son John acquired an interest in a manor farm called Muston in Piddlehinton Parish, Dorsetshire initially by copyhold. Muston Manor survives to this day.
