The Local Bricklayers No. 1 was a notable and large early union in Grand Rapids. It was involved in strikes in 1891 and 1893, over wages and hours. The collection includes meeting minutes, lists of members, financial records and some correspondence. The member lists include lists of traveling cards granted, member initiations and expelled members. The collection is strongest used as a resource for labor research, but may also provide insight into individuals who belonged to the union.

The collection also contains meeting minutes from the Stonemasons Union No. 3. The minutes begin with the organization of the Stonemasons in 1898 and end with the dissolution of the organization in 1901. The Stone Masons appear to have organized out of the Bricklayers union and then merged back in with them. The Stonemasons record book also includes lists of officers and a roll call.
