Hi Joanne:
My Grandfather grew up in Andeten Amt Hoya.
My Grandmother was a Becker. (Zeitlow, Kreis Demmin)
They had their family in Crawford County Iowa.
I grew up in the Manilla area.
If you had relatives in the Martfeld in 1852, you might want to get a copy of
the 1852 census for that area. I got a copy for the Anderten area for something
like $14. It had my GF and his entire family listed with specific information.
The following is the URL for that information:

The surname index definately shows Herzbergs in Hoya.
The following URL will show what church records are available for Martfeld.
There is very little information avail for the Hoya area at the Family History
Centers (LDS).
My parents were married in Shenandoah (Page Co.) by the Rev James Pearson, a
radio pastor.
I don't know if you have seen the following URL, but it has photos of 23
cemetary stones for Herzbergs in Page
