"Siegmund" on his death certificate, "Salomon" on his marriage certificate. In both cases his wife is named as Hedwig geb. Nothmann. I assume Siegmund and Salomon are his vernacular and Hebrew names respectively.

Siegmund Salomon's date of birth is given on the copy of his marriage certificate as 18/09/1857, while his sister Ernestine's date of birth is give as 17/09/1857 in her death certificate and 16/09/1857 in the transcription of her entry in the 1939 census. They were clearly twins and born within a day of 17/09/1857.
