One of the best surprises in my family history research has been the story of my wife’s great-uncle, Marcel Rogissart. At first glance, his records seemed straightforward—a French immigrant who settled in Massachusetts, served in World War I, and lived a quiet life after returning home. But as military records, transport manifests, muster rolls, and regimental histories came together, a far more remarkable story emerged.

Marcel was born in Charleville, France, in 1896 and immigrated to the United States with his family in 1911. He declared his intention to become an American citizen before the United States entered the war, but was drafted into the U.S. Army while still legally a French citizen. Assigned to Company D, 1st Battalion, 306th Infantry Regiment, 77th Division, he returned to France in the uniform of his adopted country to help liberate the homeland he had left only seven years earlier.

His service placed him in some of the most significant operations of the American Expeditionary Forces. The 306th Infantry learned trench warfare while relieving the veteran French 42nd Division in the Vosges Mountains, endured heavy fighting along the Vesle River, participated in the operations surrounding the rescue of the legendary Lost Battalion, and fought in the capture of St. Juvin during the Meuse-Argonne Offensive. One detail I found especially meaningful is that the regiment later commemorated the crossing of the Aire River and the capture of St. Juvin in its Distinctive Unit Insignia—a permanent reminder of one of the defining moments in Marcel’s military service.

The records also revealed something I hadn’t expected. Marcel did not return home with his regiment after the Armistice. Muster rolls show that he became ill and entered a military hospital on December 31, 1918. Months later, he returned to the United States aboard the SS Agamemnon as part of a convalescent detachment, while the 306th Infantry continued to carry him on its rolls until his discharge. Only after recovering did he complete the naturalization process he had begun before the war, finally becoming an American citizen.

Researching Marcel’s story has been a reminder that family history often extends well beyond names and dates. A handful of military records, when combined with regimental histories and historical context, can illuminate an extraordinary life. Marcel’s journey—from a boy in the Ardennes, to an immigrant textile worker in Massachusetts, to an American Doughboy fighting near his childhood home—is one of the most compelling stories I’ve uncovered in my family’s history.
