Looking for Sarah Onions of Whitehall Brosely Shropshire

Sarah Onions (Born 1787 Died 1862)married my Gt Gt Grandfather James Jackson. I wish to know more about the Onion Family. Her sisters(according to my Gt Aunt) married a (Jane Gordon?)"Pritchard", (Damaris?)"John Webb", (Elizabeth?) "George Osborne Gordon" and (?)"John Wase". I hope I have my facts straight and would also like to find out who else was in the fold. Thanks.
