Hi Angie
I've been to the London Metropolitan Archives and looked at the Foundling Hospital collection of papers they have there.
Have a look at this info leaflet
http://217.154.230.218/NR/rdonlyres/F54A5F9A-1394-406E-B971-7AFC796BE724/0/Infono31.pdfI'm literally packed and ready to go away for a few days but wanted to send you some info to keep you busy over the next 4 days. I'm going back to the LMA on Monday to see what else I can find in the petition papers, but am not hopeful for one of those, it seemd they don't all survive.
From the baptism register
Aug 17th 1846 Joseph Cookson (no 20343)
From the General Register
Date of Acception 17th August (no 20343), when born 29 May 1846, when apprenticed 3 June 1861
From the apprentice registers
Joseph Cookson (no 20343) to John Allen of 11 Harleyford Street in the parish of Lambeth, White & Locksmith
added in later
asssigned on the 23rd May 1864 to F.D. W Smith of 12 Harleyford St, Kennington in the Parish of Lambeth, Builder & Smith
He ended his apprenticeship in 1868.
I will send you a full transcriptionlater but there isn't much more 'real' info, just column headings.
Hope this helps and isn't too tantalising.
Dawn
