We have relatively long-lived ancestors showing in our lines: my father's parents lived to mid-late 80s, my mother's mother/grandmother/great-grandmother lived in their 90s and 100s. I have every expectation of living to 100!
My longest-lived direct ancestor who lived over 100 is my 2nd great-grandmother, Harriet "Hattie" Philena ORMSBEE. Here's a 1924 photo of her at 97 years of age, during a visit my grandmother took with her 5 children including my 2 year old mother, from Vancouver BC Canada to Englewood, New Jersey. She is the shortest in the photo, second from left.
My grandmother wrote on the back, identifying each person and their relation to her. I love how this photo shows relationships here. My 2 year old mother is playing with her mother's jewellery, and Madee and GreatGrandma Graves were clearly talking about something while waiting for the photo to be taken. I suspect Madee's husband, my great-grandfather, was taking the photograph.

I have a number of long-lived persons in their 90s as well, even back in the 1700s with baptism dates with birthdates as well. Of course, there are also a number of women who died young, likely in childbirth, as well as men who died before 50, perhaps in accidents or due to illnesses.
