Tracking down the past

<p>Background: I have only known my mother and she remember little of anything about my fathers/his families past</p>

<p>But today since i have decided on UCSB, she finally told me that was his alma mater and that he got in automatically because of a fraternity my grandfather had joined while at stanford. Question is, how do i find out what frat this is. It is not important, rather just something interesting i would enjoy to learn since i know so little. It, according to her was hard to get into, was during that time largely irish and may have delat with business.</p>

<p>So how can i go about searching for this?</p>
