I've known for some time that Manley Squier and Caroline Young were married* in Kent County, Michigan, in 1860, at the house of John C. and M. E. Shaw. A little time was spent trying to place the Shaws way back when, with negative results.
*Squier, Manly, Vermontville, Eaton County, and Caroline Young, Cascade (formerly of Livingston County, N.Y.) 3 May 1860, at house of John C. Shaw, Esq., Cascade, by John B. Shaw, (J.P.) Mrs. M.E. Shaw, and Mrs. Rositta [Webster] Washburn, Cascade, witnesses.
While updating the search on Mary (Alexander) Young, the 1911 death record for Mary E. Shaw, whose parents were William Young and Mary Alexander, surfaced.
In 1880, John C. (age 61) and Mary E. (age 56) Shaw were living in Leslie, Ingham County, Michigan; also in the household was Charlotte Peck (age 38). In 1900 the widowed Mary E. Shaw (who had 0 children according to the census) was living with Charlotte Peck, in Leslie, Michigan.
In 1860, the year Caroline Young was married by John Shaw in Cascade, Kent Co., Michigan, John and Mary E. Shaw were living in Cascade, according to the census.
