I forgot to add something in my initial reply. I remembered my mom's aunts and their sister my grandma. Aunts were 1903 and 1905, Gma was also 1907 like Jethro's mom's aunt.
I saw she was born in 1907. The oldest person I actually knew personally lived to be about 101-103, he was my buddy's grand dad.
The person I knew who was born the longest ago was my step grandmom. She was born in 1896 or 1898 and her one brother was born in 1898 or1899 I think. If I found it correctly, my own grandfather was born in 1894 but I really never knew him.
