September 16, 1938 — December 13, 2023

Casper, Wy


  Jeremiah Dermot Byrne, 85, of Casper, Wyoming, passed away on December 13, 2023 at his home in Casper.

  Jerry was born in Ballyfinane, Drombane, County Tipperary, Ireland to James and Mary Byrne on September 16, 1938.  He completed his schooling in Ireland and then immigrated to Prince George, BC, Canada in 1971.  There, he met his wife of 51 years, Nancy Lefevre of Casper, Wyoming.  They were married in Casper in 1972 and moved to Ireland in 1973 to manage the family farm in Cloneyharp.  Jerry and his young family returned to Wyoming in 1975 where he was honored to become a dual citizen of Ireland and America. Jerry worked as a chemist and later as a consultant in the chemical industry.  This career took him from Wyoming to Missouri and kept him traveling across the nation.  He retired and moved back to Wyoming in 2013 to help care for his mother in law, Phyllis Lefevre.  Jerry was a lifetime member and past Grand Knight of the Knights of Columbus council 1563, a founding member of the Elks Club of Lee’s Summit, MO, past president of Our Lady of Fatima’s Holy Name Society, the first leader of Fatima’s RCIA program, an active athlete-member in the GAA- the Gaelic Athletic Association, and the founding member of a traditional Irish culture and music club in Casper.

  Jerry is survived by his wife, Nancy Byrne of Casper, his children and their spouses, Brian Byrne, Louise Byrne, Kathleen Otstot, Siobhan Byrne, John Byrne, and Sarah Medcalf, as well as numerous cousins in Ireland and England, nieces, nephews, and grandchildren.  He was preceded in death by his parents and sister, Margaret Wherelock of Bristol, England.

  A Rosary and prayer service will be held on Friday, December 22, 2023 at 4:00pm at Our Lady of Fatima Church. Funeral services will be held at Our Lady of Fatima Catholic Church on Saturday, December 23, 2023 at 10:30 AM with Father Clark Lenz officiating and with Father Philip Vaske as a concelebrant. Burial will follow at Highland Park Cemetery, Casper. Bustard & Jacoby will be handling the funeral arrangements.

  Memorial donations may be made to Central Wyoming Hospice, to whom the family extends their warmest thanks.

  Jerry, or Dermot, as he was known to his family, was a devoted son, husband, and father.  Though he came to love his new homeland in America, nothing would ever diminish his love for his family and first home in Ireland.  He took pride in his dual citizenship and deeply respected the traditions and spirit of both his countries.  He was a kind and generous friend, neighbor, and family member.  Though he will be dearly missed, the love he has sown will live forever.  Jeremiah Byrne, a true son of Ireland, Ar dheis Dé go raibh a anam, “May his soul be in God’s right hand.”

In lieu of flowers, please consider making a donation to Central Wyoming Hospice.
