Margaret WARREN born 1560 married to Thomas LOWE b 1559

I have tracked my family through the Lowe side from my own Great Grandfather, Harry LOWE back to Thomas LOWE b 1559 -  He marries a Margaret WARREN (corrected by WebMaster) born in Condover.  However when I research Margaret there seem to be a few diverging options - some suggest her parents were  John WARRREN DE POYNTON  & Margaret MOLINEAUX and up from wheras others suggest a more local John WARREN with different ancestors. Has anyone done any more detailed research ?
I am a brand new member   ( 16th Oct 2013 )  and am thinking of a visit to Shropshire to further my research but would appreciate a helping hand first.
Many thanks in advance   -  Martin Adams - Wakefield,  West Yorkshire
