Francis Xavier Sis, Sr.

1942 ~ 2022 (age 80)


Francis Xavier Sis, Sr, 80 of Frederick, MD passed away on Friday, May 27, 2022 at his home with loved ones by his side.  He was under Hospice care after suffering from two major strokes, at the end of last year.  


Born February 12, 1942 in Washington, DC, he was the son of the late John Aloysius Sis, Jr. and Mary Alfia (Furnari) Sis.  He was raised in Tacoma Park, MD where he graduated from Montgomery Blair High School in Silver Spring, MD in 1959. He learned mechanics while working as a car jockey at Suburban Cadillac and Oldsmobile in Bethesda, MD.  He served his country in the US Air Force on Active Duty from 1962-1966 where he was trained in radio electronics, and was honorably discharged from the Air Force Reserves in 1968.  Frank attended aviation school in Reno Nevada in 1968 where he got his pilot’s license.  After returning home, he worked briefly at Defense Electronics and then at Watkins Johnson in Gaithersburg, MD as a head electronics technician for twenty-six years. He traveled extensively to other countries such as Egypt, China, and Switzerland to train other technicians.  After retiring, he worked as an aide in the caring of a quadriplegic gentleman for ten years.  Frank raised his family in Middletown, MD, but spent his later years in Frederick, MD.  


Frank enjoyed reading, aviation, woodworking, and taking walks with his two favorite furry York Terrier companions, Nicholas and Sonny. He will always be remembered by his ability to “fix anything”.  If he didn’t know how, he would buy a manual and figure it out before ever hiring someone to do it for him.  


Frank is survived by his long time companion, Victoria I. Foltz, his four children: Francis X. Sis, Jr of Pasadena, MD and his fiancé Tess Cadiente, Lisa J. Allen of Hagerstown, MD and her significant other Brian K. Evans, Joseph B. Sis of Williamsport, MD, and Steven C. Sis of Waynesboro, PA, his former wife and mother of his children, Charlotte L. Wiles of Terra Alta, WV, four grandchildren Mallary N. Sis of Frederick, MD, Jarrett F. Sis of Hagerstown, MD, Kayla C. Allen of Hagerstown, MD, and Kaleb I. Sis of Williamsport, MD, two great grandchildren Briana Martin and Chance Fallin, two brothers Joseph A. Sis and wife Kathleen L. Sis of Frederick, MD, Michael C. Sis of Silver Spring, MD, sister-in-law Joyce A. Sis of Harwood, MD as well as many nieces and nephews.


In addition to his parents, Frank was preceded in death by his siblings John (Jack) A. Sis, III and Charles W. Sis.
