Saml. COOPER Spouse: Lucinda HOFMAN Marriage: 07 Nov 1861, Stark, Ohio Source: Marriage Records, 1809-1916. Ohio. Probate Court (Stark County)

It has been suggested that this Samuel and Lucinda are our subjects, but Samuel was in Michigan from at least 1850 onwards, which places doubt on the connection.  COOPER is a common surname, so it is very easy to mix them up.  Some supporting evidence is needed to accept this marriage record as being our subject.

1c.  Anon.  1966.  Marriage Index:  Ohio, 1789-1850.  Liahona Research, Orem, UT (Broderbund CD-400):  There is a marriage in Scioto Co., OH, on 5 Jun 1845 between a Jacob COOPER and a Rachel BOYER.  If this couple is the one that appears in the 1850 census of Springport, Jackson Co., MI, then Rachel is our subject's step-mother, not his biological mother.

2.  A check of the 1850 census shows a Jacob COOPER (æ 26, b. PA) with wife, Rachel (æ 20, b. PA), in Springport, Jackson Co., MI (p. 390B).  They have five children, all born in Ohio:  Mary (15), Samuel (10), Elizabeth (8), John (5), Angeline (4).  Jacob's and Rachel's ages must be wrong because, otherwise, they are much too young to be the parents of these children (but see their ages in the next census).  Their son, Samuel, is almost certainly our subject.

3.  A check of the 1860 census shows a Jacob COOPER (æ 48, b. PA) with wife, Rachel (æ 47, b. PA), in Springport, Jackson Co., MI (p. 539).  They have these children, all indicated being born in Ohio:  Samuel (21), John (16), Angeline (14), Mary (5).  If the youngest child, Mary, is their daughter, she should have been born in MI, not OH — or did the enumerator screw up when transferring his field notes to the census forms because Jacob & Rachel should have a daughter, Mary, age 15, who was born in Ohio.  Their son, Samuel, is almost certainly our subject.

They are listed next to Jacob COOPER (æ 60, b. PA) and his [second? third?] wife, Eleanor (æ 45, b. PA); Jacob is almost certainly Samuel's father, with a new wife.
