Hi Sue
Am coming into the lively Durell discussion a bit late but only just found it whilst Googling. A great relief to find someone on the trail of the same Durells as me. I belong to Sarah Hannah b 1818 (I believe she's my Sarah anyway).
Sarah Durell married James Buckingham 28 January 1838 at St Matthew Bethnal Green. Sarah's father Richard Durell, weaver. James's father David Buckingham, writer. James lived 7 Grosvenor Place BG; Sarah lived 4 Park St BG.
James and Sarah's first son James Edward Buckingham born 22 March 1838 at 7 Grosvenor Place BG. In 1841 census James and Sarah at 83 Wheler St BG with Mary Durell, 60, weaveress. As you know, same census has Richard and Rebecca Durell with son Richard, plus James and John, at Grosvenor Place. No house number, but it's the seventh household from the beginning of the street on the form....
In 1851 census James and Sarah are at 53 Holywell Lane Shoreditch and with them is Mary Durell, widow, 67, weaver. You probably won't have found her in the index as "they" have indexed her as Mary Dyrell.
Given that my Sarah's father was Richard (marriage cert) and that Mary lived with Sarah till her death (1850's), and that Sarah is aged 32 in the 1851 census, I am as certain as I can be that she is Sarah Hannah Durell b 1818 to Richard and Mary, and thus sister to your Abbott. Also, James, John and Richard Durell (with Rebecca nee Bain) living at Grosvenor Place 3 years after my Sarah and James lived there, places them all neatly as your Abbott's siblings.
Only fly in the ointment is that Habbitt Durell's baptism shows "female" (can't remember where I saw this now but will look it up again later). This threw me for a while when I was also looking for your Abbott.
Sorry I didn't get into this earlier as I could have saved you all that faffing about with the other Richard Durells - there is a whole other branch getting in the way of ours at BG! Can fill you in on those if you like, but to be honest it's really good to be getting somewhere with MY Durells for a change (keep helping other people with THEIRS!)
There's more to say on all this but hope you're still out there ... how far have you gotten since those earlier postings c 2005?
