Jennie is my ggrandmother. She was married to George Washington Bunker. She was born 1840 in Pa. Died Oct.1913 Looking for any infomation on Her or her family

I recently found a letter written to my Grandmother stating that Jennie MacAbee was born in Fort Wayne, Adams County, Indiana on September 25, 1939.
I know that the birth date doesn't match but the names are the same.
Let me know if the birth date is incorrect.
