Hi Ken, the earliest plat maps available in Michigan were issued in 1859, others followed in 1875, 1897 and 1916. The 1859 plat map was issued as combination St Clair County / Macomb County wall map. It is absolutely huge and all of the townships are colored -- making it difficult to get a good copy of them. Nevertheless, here is what I found:
Clemens, P. Washington Twp, Sec. 1 (SE of Romeo); Giddings, D., K., L., N., U., all residing in Sections 4 and/or 5 of Macomb Twp.; King, O., Ray Township, Sec. 7.
