I have been able to construct a family group with census records and death records. Below is the family group:

Here is my Burkart (Burkhart, Burkard, Burkheart, Burkhardt) family:

John Burkart b.c. 1815 Germany
Pauline Burkart b.c. 1818 Germany
Frances Burkart b.c. 1841 Germany
August Burkart b.c. 1843 Germany
Leopold Burkart b.c. 1846 Germany
Joseph Burkart b.c. 1850-1852 Germany or Ohio
Caroline Burkart b.c. 1856 Ohio
Charles Burkart b.c. 1855 Ohio) family:

John and Pauline were in Cincinnati for a short time, and then went to Hamilton, Butler Co., where they lived the rest of there lives. Joseph, Frances (married Fey) and Caroline (married Grimm) also lived and died in Butler Co., Ohio. Tom and Charles supposedly 'went west', I am assuming west of Ohio, and I have found nothing on Leopold yet. If anything rings a bell, please feel free to ask any questions.
