Partially due to difficulty establishing you have the right person, I don't tend to research deaths much unless it is to establish death of a sibling of the same name. However I do have a copy of the Gloucestershire FHS Burial Index on CD and have just found the following :
Ann Meek buried 25.12.1837 age 47 Ampney St Mary
Hannah Meek buried 31.12.1837 age 95 Ampney St Mary
The only Giles listed was 2.4.1823 age 16 - so no connection.
I also have the National Burial Index on CD and listed were :
Ann Meek 27.6.1814 Age 20 Ruardean
Ann Meek 6.9.1825 Age 77 Ruardean
No Giles listed
One tip if researching MEEK is that early records (and I mean earlier than 1800) often list MOOK.
Note also that there is often a tie in between Hannah and Ann, but not often between Rosanna & Hannah, unless misheard by the enumerator

Good Luck

Jim
