I have a record of 12 children of Philip Gunter & Mary Tylor. They had a son James born 23 Jan 1823(11th child), so I suppose he could be the father of your James? I'm sorry I don't know any more, as my interest here lies further back from Philip and Mary.
My great grandmother Elizabeth Gunter was a granddaughter of Philip and Mary and she married Joseph Amer and moved to Yorkshire in the mid 1850's where my research continued for the 1860's.
I can give you details of the other 11 children if that will help. As far as I can tell, Elizabeth only had one sister Ann.
