James "Jim" F. Grubb

November 18, 1938 — February 4, 2023

James “Jim” F. Grubb, 84, of Byron, IL passed away on Saturday, February 4, 2023, following a long battle with cancer.

He lived an incredibly active life, working into his late 60’s. Along with his wife of 64 years, they enjoyed traveling, spending time in Hawaii, Alaska and exploring the continental US. A fan and ardent supporter of the Phantom Regiment, James donated his time driving bus, helping cook and cheering on his favorite corps. A lover of nature, James led multiple Boy Scout troops up the Tooth of Time in Philmont, NM, cultivated natural IL prairie grass on his acreage and experimented with dandelion beer, though few encouraged him to continue as brew master.

James is survived by his loving wife Betty (Brinkmeyer); sons Gregory (Judy) Grubb, Bradley (Lynn) Grubb, daughter Marie Grubb; grandchildren James Grubb and Shannon (David) Lawlor, Jenna (Alex) Sedlacek and Tyler (Sarah) Grubb; great-grandchildren Peyton and Ethan Grubb, Michael and Jacob Lawlor, and Logan Sedlacek; brother Jerry, and sisters Charlene, Judy, and Nancy; many nieces and nephews. Preceded in death by his parents Clarence and Margaret, brothers Clare, Gordy, and John.

The family would like to extend our tremendous thanks to the girls at Rochelle Rehabilitation in Rochelle, IL who treated Jim with care and love. Additionally, we would like to thank the dedicated team of professionals at Northwestern Memorial Hospital and OSF / St. Anthony's Hospital in Rockford, IL.

Visitation will be held from 10:00 a.m. – 12:00 p.m. on Saturday, February 11, 2023 at Fitzgerald Funeral Home & Crematory, 1860 S Mulford Rd. Rockford, IL 61108. Those unable to attend services may join via Zoom. Meeting ID: 83058158466 Passcode: 1234
