Hello Milt
I would think they are two differant John Bagshaw’s
For your interest here are the Bagshaw’s from -
Dewsbury Parish registers 1538-1653 -
John, son of James Bagshawe, bapt 07 Sep 1604.
Richarde, son of James Bagshawe, bapt 19 Aug 1608.
William, son of James Bagshawe, bapt 22 Mar 1611.
[omitted], daughter of William Bagshawe, bapt 20 Nov 1612.
James, son of James Bagshawe, bap 20 Apr 1622.
Marye, daughter of William Bagshawe, bapt 13 Jun 1639.
William, son of Richard Bagshawe, bapt 17 Feb 1641.
Jonathan, son of Richard Bagshaw, bapt 28 May 1645.
Sarah, daughter of Will Bagshaw, bapt 25 Sep 1645.
Joseph, sone of Richard Bagshaw, bapt 06 Apr 1651.
James, sone of William Bagshaw, bapt 17 Jul 1653.
Sarah, daughter of John Bagshaw, born 28 Aug 1653.
09 Apr 1563 John Conyer had a child baptised named Thomas.
If the Masbrough is near Rotherham there is also
John Bagshaw, w., & Ann Rodger 05 Jul 1798
And
17 Mar 1777 John Bagshaw and Sarah Shaw of Wath
So John Bagshaw is a fairly common name as are iron founders, I would be looking in the Dewsbury registers for Sarah Conyer nee Bagshaw and her history, someone may have the 1653-1837 ones.
