Salomon Guetermann - Moritz and Maurice

Mathilde Goldberger
Mathilde Guetermann

The manifest of October 23rd 1882 provides the names of Samuel, Mathilde, Max, Moritz, Paul, Carl and Lena Goldberger en route to New York from Bremen.

On evidence available, Mathilde Rosenwald had first married sometime during or before 1870 to Salomon Guetermann (15th January 1847 to 3rd October 1876; Salomon died young at the age of 29). The records are very odd, date‐wise, in that Mathilde's two boys, Maurice and Carl (with her second husband Samuel Goldberger) were born in 1872 and 1875 respectively, while Salomon Guetermann was still around, reportedly dying in 1876. Salomon's son Paul Guetermann was born on November 27th 1872, the same year as Maurice Goldberger, Samuel Goldberger's son was born. The 1900 New York Federal Census has 1890 listed as the date of her marriage to Samuel Goldberger, preceeding only the births of her daughter Lena and son Norman. I am beginning to wonder whether Salomon Guetermann and Samuel Goldberger were the same person:

Paul Guetermann born November 27th 1872
Maurice Goldberger born November 1872 in Germany?
ancestry.com shows a Samuel Guetermann as father of Mathilde's daughter Lena: (please see a Wertheimer Family Tree by Istvan Esteban Reti Waller):
"Life story: Samuel Guetermann was born in 1848 in Emershofen, Bavaria, Germany. He had one daughter with Mathilde Rosenwald de Guetermann in 1881. He died in 1905 at the age of 57."
By the same reasoning, could it be that Mathilde's sons Maurice and Moritz are one and the same? There's no "Maurice" on the Werra manifest; only Moritz.

The manifest of October 23rd 1882 provides the names of Samuel, Mathilde, Max, Moritz, Paul, Carl and Lena Goldberger on board the SS Werra.

I'm hoping for help and additional information here. I'm making a study from photographs of visitors to Norman Goldberger (Mathilde and Samuel Goldberger's son, born in NYC) probably to do with Hops trading towards the end of prohibition. Many thanks.
