You are right, there are lots of Turkes in Long Newton, but I couldn't find your Sarah, although I searched from 1685 to 1710 in the PR. There seem to have been two families around the right time in Long Newnton, or possibly one man, Thomas, with two wives, as I notice that his first bunch of children were with Elizabeth (Jane 1685, Thomas 1691 and John 1692), followed by children of Thomas and Anne - Jane 1694, William 1696, John 1698, Richard 1700, Anne 1701, Mary 1706 and twins Isaac and Rebecca 1709. There is a member's submission (beware!) for a marriage of Thomas Turke and Elizabeth Moody in Long Newnton on 30 April 1685
I didn't find any Davies families in L.N. at all.
I'll be in the RO again next week, if there is anything you want me to follow up.
