I am trying to find the family (parents, siblings) of my great-great grandmother Elizabeth BUSTER. In the 1861 census she is 82 yo, listed as born in Tiverton, Devon. In the 1871 census she is 92 yo, listed as born in Bampton, Devon. She married Samuel ALVIS 3 Apr 1808 in Clevedon St Andrews (Somerset). She died in Tickenham age 101 on 4 Apr 1880.
In the 1841 census she is listed as born in Somerset, and is 60 yo. In the 1851 census she is 72 yo.
Baptism certificate would be great.
