You were probably as surprised as I was to see how many Creswell Tayleurs are actually listed on the IGI records. I imagined that with a name like that there would be very few, and I still can't believe that they aren't all related in some way.
I haven't researched them in detail and hopefully "ValsGranddaughter" can tell you more than me. I was investigating the Tayleur family for property connections rather than the family tree per se. ValsGranddaughter is a direct descendant of the Cresswell Tayleurs mentioned in the earlier postings, whilst I am descended from the first Cresswell Tayleur's Uncle Richard. I also know that the spelling between Taylor and Tayleur can be interchangeable.
I also suspect the first Creswell Tayleur's daughter, Margaret Tayleur, married a John Taylor as shown on the Cheshire Visitation. I suppose they could have had descendants named Creswell Taylor, but I ahven;t explored this family at all.
I have checked my family trees and cannot see any obvious connection to either the St Chad's or the St Alkmund's Cresswell Tayleurs. (By this I mean that I cannot see any obvious male sibling lines on my charts that haven't been followed right through and there is no mention of these Creswells.) I have also taken a quick look at the IGI postings and have made some comments below. You are welcome to send me an IM and I can give you more information about the ones I know about, but as a starting point I think your best bet is to explore the ones that I don't know anything about.
Taking the IGI records for "Creswell Tayleur" in turn, the ones I don't know about are as follows:
Birth about 1614, son of John Tayleur and Margaret Creswell - I know about John and Margaret and therefore I think this record is eroneous. Margaret Creswell died in 1601; I have a copy of her will.
Birth/christening 19 Sept 1677, London to Isaac and Elizabeth. Whilst it seems unlikely that a London family is linked to Shrewsbury, you should be aware that one of my Shropshire Cresswell Tayleurs married his wife in Westminster Abbey. The Bolas Magna Tayleur's were reasonably wealthy - Barristers and Clerics in the main, but also marrying into well known Shropshire families. It is possible therefore that if your Creswell Tayleur is related to ours, albeit a long way back, he too may have come from a wealthy family.
Similarly I know nothing about the christening 30 Aug 1693 at St James Clerkenwell son of Isaac & Elizabeth - did their first son named Creswell born 1677 die young?
Christening 02 June 1693 at Upton Magna, son of Thomas and Ann - this location fits best with a potential Shrewsbury family.
Birth 26 Feb 1707 in London to Thomas and Cecilia - same comments as above
Birth 1711 of Bowles Magna - this is another eroneous entry - I think the correct baptism date is 1721.
Marriage 15 Oct 1769, Marylebone, to Sophia Brill
Christening 26 Dec 1779, St Chad's Shrewsbury to Creswell and Elizabeth - see below
Christening 22 Jan 1815, St Alkmund, Shrewsbury to Creswell and ELizabeth. Based on dates, I don't think this could be a second (repalcement) son for the previous entry. Were there two generations of Creswell and Elizabeths?
Marriage 17 June 1788, Frodesley to Ann Lawley - again this location fits reasonably with Shrewsbury.
Christening 9 Oct 1838, Toxteth Park, son of William Holbrook Tayleur and Emma Elizabeth.
Christening 25 July 1844, Surrey, son of William Holbrook Tayleur and Emma ELizabeth - at first I thought this may be a replacement son, but then the dates don't fit with the 1881 census which indicates the 1838 date is more likely to be correct.
Marriage 26 Aug 1839, Birmingham to Sarah Wilkinson - could this be the Creswell who you found a burial record for in Birmingham?
I am sorry I can't be more helpful
