From THE UNTERRIFIED DEMOCRAT, August 26, 1915 The remains of LORENZ STRAUB, an old and respected citizen of Morrison, who died Saturday, August 14th at the age of 78 years, were laid to rest in the Cleary Cemetery, about one mile west of Morrison, on Tuesday, August 17th, 1915.  He was buried with Masonic honors by Chamois Lodge No. 185 A.F. & A.M. assisted by members of Linn Lodge No. 326, and Hermann Lodge No. 123.   Mr. Straub was born in Wheeling, West Virginia, April 9, 1837, and has lived near Morrison for many years.  He became a Freemason more than forty years ago.  He was not a member of any church but lived an honorable upright and exemplary life.  Mr. Straub was never married but leaves a host of near and dear relatives to whom we extend our heartfelt sympathy.
