I am not related but wanted to help. There is a Samuel and Margaret Inbody/Imbody in 1860, 1870 and 1880 US census Iowa Linn Co College. 1860 lists INBODY Samuel 44, Margaret 35, Ephraim 16, Lewis 15, Henry 13, Catherine 11, William 9, Chris 4, Samuel 2, James 4/12 Samuel & Margaret b OH First five ch b IN last four in Iowa.
In 1870 IMBODY Saml 54, Margaret 44, Ephraim 26, Lewis 25, Henry 23, Catherine 22, Wm 18, Lucious(?) 16 Christian 14, Saml 12, James 10. in 1880 the older children have left home and only James is at home. An Ancestral Chart at FamilySearch lists Samuel Inbody b 27 Dec 1816 Hocking OH son of Jacob Inbody & Catharine Shaffer married Margaret Williams Mar 1842 Elkhart IN Margaret b 14 Feb 1826 Muskingum OH. I don't know what documentation the submitter has. IN State Library database online does list the marriage of a Samuel Inbody and a Margaret Miller (Williams)on 6-2-1844. Look for this family in 1850 IN Elkhart Middlebury.
