Manker was born near Darlington, Indiana. He served in the Civil
War, and was injured in the knee, which left him a cripple for life.
He was married to Sarah Elizabeth Winter, who also lived near
Darlington. They had a flour mill there and later moved to Red Oak,
Iowa, where he operated a flour mill. Later they moved to Elliott,
where he was in the banking business for a number of years. Seven
children were born to Mr. and Mrs. Manker: John, Roy, Orville, Dean,
Mary, Fanny Manker Redmon, and Grace Manker Humphrey. All are
deceased now. Henry and Sarah were faithful and devoted members of
the Methodist Church in Elliott.
