Researching Peter Bertram, b. 22 March 1818 in Germany. Immigrated in 1842 on the ship Argo from Le Havre, landing in NY. Was married to Louisa Rittersbacher ( daughter of Nicholas & Christianna Rittersbacher) in 1844 in Lebanon County, PA. Don't know if Peter & Louisa knew each other prior to immigration or if it was a ship-board romance; the story goes that they went their separate ways after arriving in America, but apparently stayed in touch, with him going out to marry her & bringing her back to Plymouth, Luzerne County, PA where he had settled.
They are on the 1850 Plymouth, Luzerne Co. census. On subsequent censuses, they both indicated they were born in Bavaria. Peter was a stone mason & they were Protestant.
Their children were: Albert R. Bertram (my line; m. Emma Elizabeth Ransom), Catherine (m. 1)Ziba Major, 2)Ransom Elston), Peter (m. Adelia Ransom, Emma's sister), Elizabeth (m. Charles Henderson), and Christianna.
I have much info going back on the Ransom & Major lines but nothing on Bertram & Rittersbacher in Germany.
Thank you!
