1840 Census? This is hard to read since its a copy but Adam Albrecht (Zena's Great Grandfather) is near the bottom. He had 2 children under 5 and both he and his wife were between 30 & 40. If im reading this correctly.
1850 Census Adam Albrecht
1860 Mary Albrecht (After Husband Adam's Death? Although I have in my records that he died around 1893?)
1880 Richard Jacob Albrecht
