Having had a father born in the early 1900s, I know how hard a hard life many of that generation had dealt them.
In spite of whatever hardship, she had to be a woman of great character to have raised such a fine person as you.
Rejoice in the fact she's finally free from such a horrible & debilitating disease, and now resides in the Kindom of Heaven.
...our prayers for her, my friend.
