Thanks very much gain. I did order that death certificate for the Elizabeth Berry who died in 1857 but unfortunately it wasn't the right person, as it was for a much younger woman. In 1861 the Noble family had moved to 7 Arthur St Peckham, parish of Camberwell, borough of Lambeth, and there are a couple of possibilities for Elizabeth in Camberwell betweeen 1851 and 1861, so I probably should order one and hope it is the right choice, and if not I may have to order both. Some Councils, such as Durham CC, are very helpful, and will tell you which certificate you should order, but Southwark didn't provide any assistance after I emailed an enquiry to them recently. English certificates are generally not as useful as those in Australia, which often provide maiden names, spouses and children's details, but at least it would confirm date and place of death.
Maria married in the same church as her sister Jane, who was married there to Thomas Key in 1837, and in 1841 parents William and Elizabeth Berry were living with or next door to Jane and Thomas Key, in Great Exeter St Marylebone. Father William died in 1843, at 16 Weston Place, London. His burial is on the London Deaths and Burials records on Ancestry, and at that time the Key and Noble families must also have been living at the same address, as several of their children were born there between 1843 and 1845. The Key family emigrated to NZ in 1856, but I'm not aware that any Noble family members followed them out there.
Cheers,
