Rebecca (Wilkerson and/or Turner) Bottom - Thomas Bottom's wife

The wife of Thomas Bottom is sometimes seen on internet sites as Rebecca Wilkerson and sometimes as Rebecca Turner. Thomas' will has both a son Wilkerson and a son Turner. My guess is that either he had 2 wives, or her name was Rebecca Wilkinson Turner Bottom.

I have not found any reliable sources that would prove it one way or another. Any reliable documentation would be appreciated.
