I am trying to find the baptism of two children of Thomas Harpur & Sarah Walker [married 11-06-1770 Mickleover Derbyshire]. Their twin sons Joseph & John Harpur were both Brickmakers in Derbyshire and most likely born around 1781. I have those of their brothers & sisters, but somehow can not locate them; it should exist in the parish register or Bishop's Transcripts, but doesn't appear online. Perhaps in the Derbyshire Records Office. They also have non-conformist records, so I am told.

William son of Thomas and Sarah HARPUR was baptised January 18th 1785 (St Peters).
James son of Thomas and Sarah HARPUR was baptised October 24th 1786 (St Peters).
George son of Thomas and Sarah HARPUR was baptised October 5th 1788 (St Peters).
So four males were baptised to Thomas and Sarah HARPUR. There is however a gap between 1779 and 1785 when it is possible that two other children could have been born.
Thomas Harpur & Sarah Walker could be found in the 1809 census which I do not have.
I reside in The Netherlands and need any help I can get.
