Re: GARRETT & Associated Families

I have just been given a copy of "The Garrett Family" by Archibald F Bennett dated 1956 - he has Jane dau of John Garrett and Jane Quayle chr 29 Sept 1822 buried 2 Aug 1823 - I have not checked anything in this having received it in post yesterday.
According to him John was son of John G. and Ann Kewin/Cowin.
Is this history known by Garrett family members to be inaccurate ? - there are a few funnies on first reading but the few points of ref I have with other info seem to be included
