It does appear to be the family. I will check out all the links you've provided, thank you :)
I've just peeked at the http://roots-and-boughs.com/Kathy's%20Lines/herring.html
link and it would fit as it is said he had sister(s) living in the USA. Interestingly there aren't any children listed as having been born in Germany...
Peter Pries and Friedrica Unknown had the following children:
8. i. AGNES6 PRIES was born in 1852 in Scott Co, IA. She died on 10 Jun 1907 in Davenport, Scott Co, IA. She married Marx Eckmann on 30 Dec 1872 in
Pleasant Valley, Scott Co, IA. He was born in 1842. He died in 1950 in Davenport, Scott Co, IA.
ii. AMELIA PRIES was born about 1854.
iii. OTTO PRIES was born about 1854.
iv. PETER PRIES was born in 1861 in Pleasant Valley, Scott Co, IA. He died on 21 Dec 1890 in Davenport, Scott Co, IA. He married Friederike Beinke on 21 Feb 1886 in Cleona Twp, Scott Co, IA.
I've just had a look at some of the findagrave's and I'm getting very confused which is easy to do I know!
There is a Henry G Pries buried at Section 2 lot 99 which is where Peter and Friedreka are buried. His birth 1843 in Germany.
it does look like the Pries of Davenport Iowa are all related but how *scratching head* and my John Henry Peter Pries born 1841 Germany, died in Australia.
I suppose I was hoping for an immigration to the USA record listing his parents to solve the puzzle but I'm guessing their just isn't one.
I will continue with the links you have so helpfully given me and something might just pop up.
Thanks for all your help jimkido
