Okay...update time.
I have been on this all day now and most of the last two days, the Frederick/Angelina tie up is the wrong one, I actually have this cert' from only last week.
This then, becomes incredibly mind numbing from this point on.
The, hopefully, real grandmother is the 1884 birth at Shaftesbury. It has to be the one, as her name is spelt with a E in Maude, the other one isn't, the E stands for Ethel in that one....
The original enquiry was about a William John Stainer, I thought I was right about him, but, again, I was wrong

In fact, the help on here has sent me on a Richard William George Stainer tack instead.
If, and do hope if, the Richard William George Stainer is the one that drowned in the submarine C11 is my grandmothers brother, then a whole raft of other Stainers show up on the census reports. I have copied these all down and can track related folk back to the 1841 census, it then fragments awfully...
The drowned Richard (isn't it awful how I talk about the poor chap), also has a father Richard, who's father was a Charles and down to about 1851, when there are about five Charles Stainer's, all born around Shaftesbury.
It has taken forever to translate the spelling on a lot of documents, but it does look positive for once...makes a pleasant change.
I choose to write stuff in longhand with a fountain pen and have dried up an ink cartridge on this family alone in three days. I have to confirm all the above before transferring to p.c., I am going on holiday, I think, instead...
