From Alice Walz, Leon, KS: She writes: "My sister, Mary Lou Ireland, my husband, Doyle and I were very happy with our Ingalls research in the Naperville, Joliet, New Lenox, Illinois area.
"We found the graves of Louis Ellsworth Ingalls (#2792 in Burleigh's book) and most of his family in Oakwood cemetery in New Lenox, Will Co., IL. Also Abner Ingalls and family. In Naperville, we came across graves of Henry #2791) and Lois (Royce) Ingalls. We were checking on the Royce name in old Boardman cemetery and discovered the Ingalls graves. We were surprised to find the grave of Andrew (twin brother of Abner), who had died in Tennessee during the Civil War. We had stopped in Tennessee on an earlier trip, looking for his grave. A sexton in one cemetery told us that some of the people in the south were not happy having Union soldiers buried in their cemeteries, so some bodies had been moved. We really had given up on finding his grave.
Henry married Lois Royce, daughter of Jonathan Royce and Mary Emery, on an unknown date. (Lois Royce was born on 12 Jul 1803 in New York - New Hampshire, died on 30 Jan 1855 in Naperville Dupage Illinois and was buried Boardman Cemetery in Naperville Dupage Illinois.)
