As seen in the tree - there is already a daughter called Margaret for this couple - she married Laurence Warren of Poynton (Pointon), not Robert Warren of Wissington. Sir Piers Legh of Lyme & Ellen Savage did not have two daughters called Margaret.
No daughter of this family married Robert Warren - a farmer of a Warren family from Suffolk. (& looking at his profile I can't see where the surname Legh (Leigh) for his wife Margaret has originated from - there doesn't seem to be a source for it. It looks to me like an attempt at providing family links for the alleged descent of John Bigelow from the Baguley family of Cheshire - a descent that is problematic - not least for being mixed by the wooden spoon of Horatio Gates Somerby.)
