Thank you both so much
I didn't know the new year was at a different time back then! Will process the info in your posts later and see where it leads.
Ciderdrinker, I had seen about Lydia's marriage to Onesiphorus Pass before .. will have a look at the other details too later on.
Thank you for the tax records too - I hadn't seen that before. He's an elusive chap!
I have seen a lot of refences to William Daltrey/Daltry in the late 1600s and early 1700s (will try to dig out the info later) and I suspect he may be James' father (particularly as James named his first child William) but I can't find anything concrete at all.
London land tax records
William Daltrey – Farringdon Without, City of London – 1692
William Daltrey – Vintry, City of London – 1725/1726/1728
There is a William Daltrey who married Jane Willsford and they had three children but I can't find any evidence of James being one of their children and I suspect he was born a little too late.
William Dolltrey m. Jane Willsford 04 Apr 1689 (Saint James Dukes Place, London)
Samuell Daltrey b. 1689 (St. Lawrence Jewry and St. Mary Magdalen Milk Street, London)
Susana Doltrey b.1697 (Saint Martin – Vintry, London)
Willsford Daltrey b.1705 (Saint Martin – Vintry, London)
James was born around 1715/1716.
I have also seen the (many) family trees who make the connection with the Yorkshire/Pontefract Daltrey but I don't think it's right either. It makes no sense and I think it's just a case of one person making an incorrect link between two different James Daltreys and then everyone else has copied it.
Thank you both again for your thoughts any other light anyone can shed would be most welcome
