I have looked at the parish register of Bardwell 1800 to 1837 in respect of Staley’s. It reveals:
Baptisms
20 Oct 1816 Eliz Stely daughter of Wm and Mary, farmer otp
14 Mar 1819 Ellen Stely daughter of Wm and Mary, farmer otp
15 Apr 1821 Caroline Stely daughter of Wm and Mary, farmer otp
29 Aug 1824 John Staley son of Wm and Mary, labourer
24 Sept 1826 George Staley son of Wm and Mary, labourer
11 Jan 1829 Caroline Staley daughter of Wm and Mary, labourer
15 Jul 1832 Moab child of Mary Staley of Bradwell, lacemaker
15 Jul 1832 Midian child of Mary Staley of Bradwell, lacemaker
10 May 1835 Mercy illegitimate daughter of Mary Staley of Bradwell, lacemaker
26 Feb 1837Mary/Mercy illegitimate daughter of Elizth Staley of Bradwell, lacemaker
Marriages
There were no Staley marriages in Bradwell in this period
Burials
25 Nov 1827 Caroline Staley aged 6 (born c1821)
13 Nov 1833 Moab Staley, infant
12 Mar 1837 ? (possibly John) Staley aged 13 (born c1824)
14 Oct 1842 Caroline Staley of Newport Pagnell (workhouse) aged 14 years. Is this the Caroline born 1829, but there is a Caroline Steele aged 11 on the 1841 census in Newport Pagnell
15 Feb 1844 Mary ? of Bradwell aged 20, not sure who this is.
Conclusions
1. The Wm and Mary, farmer and the Wm and Mary, labourer are the same couple as the birth, death and second birth of Caroline indicates.
2. There is no indication what happened to William after 1829 for sure but a William Staley of Buckinghamshire was sentenced in summer 1829 to 7 years transportation for trying to aid a prisoner to escape from jail. Letter of 29 Aug 1829 to remove Wm Staley (and other prisoners) from the jail at Aylesbury to the Leviathan at Portsmouth. The trial at Buckingham on 27 July 1829 gave his birth date as 1791 and prisoner number as 9472 (Series HO8 – national archives). Sent to NSW 19 June 1830 on the Royal George (Series HO8 – national archives). So this would indicate that William is not the father of Midian/Midiah/Media. He arrived in Van Diemens Land (Tasmania) on 25 February 1831
3. Midian could be Midiah as the final letter was suspect and could have been a poor h. It is not much of a jump from Midian/Midiah to Media. Also the 1832 baptism ties in with the birth year recorded on her burial record
4. The 26 Feb 1837 baptism was transcribed as Mary but the original looks more like Mercy to me. I think the Mary and Elizabeth in the 1835 and 1837 baptism could possibly be mother and daughter.
