Thanks everyone for your input and info
The reason for my question was that the patronage and advowson of the Layston church in Herts was held by the Crouch/Crowch family for generations (They're also my ancestors). When the Crouch's married they seemed to only marry into about half a dozen different families. These families intermarried over and over again.
Then I have my John Turner (B: 1603, educated at Cambs Uni) as the Vicar of Layston from 1650 'til his death in 1663 (I have the PR's with his signature on each page and his death notice as Vicar)
John's grand daughter married Thomas Crouch c. 1690.
There are two marriages that may be part of my lot but I'm wondering if I clutching at straws here

John Turner married Mary Crowch in 1600 at Layston
Margaret Turner married Richard Crouch 1604 Layston
Because the Crouch/Crowch family were one of the VIP families of the area, I was trying to work out if a normal everyday Vicar could be related as I can't
prove any connection - except circumstantial at this stage.
The only other "thing" that I had was that, over the years, some of the other clergy at Layston were connected to the few families that the Crouch family had married into.
Sorry - that wasn't meant to be so long-winded and garbled.
I'm really trying to work it all out in my own mind - and failing at the moment

and I just hate it when I can't totally PROVE a connection.
