Let’s take a look at my family tree. We meet the niece of my 3rd great grand uncle.
She was the third of six children born into the marriage of the bricklayer Joachim Heinrich HENNINGS and his wife Maria Dorothea Elisabeth née EVERT.
I found her confirmation entry from April 18, 1886 in the church of Diedrichshagen, Mecklenburg-Schwerin, Germany:
On December 4, 1891 Helene married Hans Wilhelm Johann BAUMANN, a farmhand born in Barendorf, Mecklenburg-Schwerin, Germany
The 1900 census of Mecklenburg-Schwerin shows her living in Wüstenmark.
So far I didn’t find any children for the couple.
