There appears to be a problem with the connection of Giles Butts to Sir Edmund Butts and Anne Bures.
Giles Butts, Sr.
Others have shown this as questionable.

The fact that records say that there was only one heir is problematic. Anne was said to be the sole heir. Also, Giles birth date presents a problem.
Listed as only child here.
