"Our sister Eva Barbara Wolfmeyer passed this life blessed in the Lord on this date 2 December in this year in Town Woodville, Calumet Co., Wisc. She lived 42 years, 4 months, and 14 days. She was born a Kellermann in Bonifaciusweiler, Württemberg. She married Johann Georg Wolfmeyer in 1857 and who came in the aforementioned year to this country, settling down first in Waukesha, Wisc. and came in 1864 to the above mentioned area. Here in the year 1865 she joined the Evangelische Gemainschaft and she converted later in 1869 under the guidance of Brother Johannes Koch. She lived since she converted a devout and virtuous life and remained true to God and the Church until her death. We lost in her one of the best members. The deceased lived with her now mourning husband for over 21 years in married bliss. She had 12 children, three preceded her in death and 9 survived her. She was survived by her parents and one brother in the old country. Her sickness in the opinion of the doctor was rheumaticus and water retention, she suffered for 9 months. While she was sick , this writer visited her often and found her always trusting in God. Many mourners attended her funeral. The sermon was from Isaiah 38, 1. May the Lord bless the surviving family."
(Note: it is speculated that she suffered from rheumatic fever, causing congestive heart failure/edema.)
