On a return visit to Rhineland 23 May 2009, we found a plywood sign had been erected at the rear of the cemetery. Our photo of the sign appears above. Our as-is transcription of the sign:

St. Peter's Lutheran Church
More than one hundred and fifty years ago, a number of familes enigrated from Germany to Middleton township seeking civil and religious liberty. As early as 1848 the settlers of Lutheran faith gathered in homes for Sunday reading services. However on Feb. 28 1854 the first Lutheran service conducted by a pastor, was held in Middleton Twsp. On April 3 of the same year St. Peter's Ev. Lutheran congregation was organized and became affiliated with the Missouri Synod. Three acres of land, a part of Lot 36, Con. 2. S.T.R. was donated to the congregation on which to build a church school parsonage & cemetery. It was on this property that the first church building was erected, a log structure 22 ft. wide, 32 ft. long. On April 14, 1858 it was dedicated to the Glory of God. Eight years later a second frame church was erected. This time a more suitable property was chosen at Rhineland, a place one-half mile north of the first site being the present location of St. Peter's Lutheran Church situated 3 miles west of Delhi and one mile south. The first parsonage was later moved and converted into a school. The cemetery on the original property is still preserved and restored. It was not until 1913 that a larger ediface of brick was constructed. Unfortunately, it was destroyed by lightening in September 1937. In May 1938 the construction of the present beautiful church was completed. This brief history of the first Lutheran church in this community is a constant reminder of the boundless blessings from God.
