Just a "pure shot into the dark":

The village of Suttorf, Lower Saxony, was part of the parish Basse, Lower Saxony.
Church books of Basse are online available at Archion here:

However: in 1844 no person with the family Helfers was born / baptized in the parish of Basse.
The very first birth / baptism of an illegitimate boy child Helfers in Suttorf / church book: Basse was in 1849

(The name of this child is mentioned in the emigration note which I linked above!)
At the time of this birth / baptism this child's father lived in Osterwald (today: part of Garbsen, Lower Saxony)

That tree provides a lead to the village of Marienwerder, Lower Saxony. These church books are also online available at Archion:

However: in 1844 again no person with the family Helfers was born / baptized in the parish of Marienwerder.
Bottom line: yes, the family name Helfers did exist about 1840 in the former Kingdom of Hannover, but it's still somehow like finding the needle in the haystack.
This is your tree, right?
