St Peter Church and Both of the parish of Bradford
Danial Mortimer Bapt 7th June 1723 Father Daniel of Clayton Thornton Sub Chapelry of St Peter Bradford (Parish entry is very poor but just vaguely readable)
Daniel married & Ann Rushworth married at St peter Bradrord 20th Jan 1747 as IGI Parish
church register not on fiche but on B/Trans at York Borthwick institute Chapelry unknown yet
Father Daniel sn'r needs more Study as Bapt unknown and I think married twice first unknown to a Deborah
and She died 1723 March (son Daniel birth maybe) Daniel 2nd marriage to Dorothy Scott 2nd Dec 1724
There is no record of Daniel Senior at Bradford or Clayton prior to 1723 and suspect Northowram
Halifax may hold this info
foot note:- St James Thornton Chapel has its own little parish register that looks like it been through the Wars and in a right old state of affairs with scribles ( Clerk trying to work out the year April to March) upside down entries of events other than BMD's also little torn note's stuck on with a few mouse holes & ink blots.(Looks like my school books age 10.)
