There was a big O'Leary family in the Fresno, CA area. A John & Louise O'Leary that I knew well. John died somewehre in the 70's and Louise I beleive in the 80's. Both buried in Fresno. John was a fireman in Fresno and might have been related to your Great Aunt. They had 1 son who died in the last 15 yrs, Russell[lived locally]. Hope this helps.
