I found an article on rrlcnewspapers.org from the 1986 Catholic Courier, in which the Kester Family is discussed. They had 13 children and their youngest graduated from Bishop Kearney in 1986, which would put her at about 17 if she was born in 1969. http://18.104.22.168/catholic-courier/search.html
and search "13 children". It should be your second result.
Best of luck!
