Lovely photo...love the hat on the right

The 1901 has 4 Ann Williamses living in Dolwyddelan, one a child and the other three born in 1847, 1851 and 1867. In 1901 the 1851 one was head of family.
This one would seem to have a husband seated next to her.
So...if that's her husband...is she the 1847 or the 1867? Does she look 60, or does she look 80? And if she's the 1847 one, what are the chances that her husband has also lived as long?
Any other possibilities? And isn't this fun?
