I don't know if this is any descendants of your Mulligan family, but I have an obituary notice from the Fresno Bee dated December 28,1990 as follows:
Eileen Mulligan Hurtado, Kingsburg... The rosary for Eileen Mulligan Hurtado, 34 will be recited at 7 p.m. today at Holy Family Catholic Church.Mass will be celebrated at 10 a.m. Saturday at the church. Mrs. Hurtado died Wednesday.She was a secretary for the Fresno County Department of Social Services. Surviving are her husband, John; her parents, Johanna and Arthur Mulligan of Selma; a brother, Gerry Mulligan of Selma; and two sisters Terri Bogart of Templeton and Jackie Perry of Kingsburg. Creighton Memorial Chapel is in charge of arrangements. I am not related to this family, just trying to help with your genealogy research.
