If this is the Margaret Brew you are referring to : BREW, Margaret [year] 1878, parish Maughold, Arch. will, no.4, LDS film no.0106486 [from Brian Lawson's website], all you need to do is order the film from a LDS family history centre and look up will no.4. It will probably have any litigation etc. as attachments included on the film at no.4.
