I did not find John Sterenberg, but i did find Jan Sterenberg. He married Martha Oosting 20-03-1890 in 't Zandt, Groningen, the Netherlands.
Jan was born in Godlinze, Groningen, the Netherlands.
Martha was born in 't Zandt.
The parents of Jan are Jan Eltjes Sterenberg and Anje Bouwman.
The parents of Martha are Pieter Oosting and Sophia Heukers.
When they married Jan was 31 years old, Martha 24 years.
Was one of the children born before the weddingdate of Jan and Martha?
Please let me know if this is the right family. When they are i will search further for you, i think there is more to ffind.
