Dear Peter and all list-readers,
all the other people mentioned seem to have surnames. I just looked up: name adoption was „forced“ in Mainz from 1808 on, yet there have also been Jewish families in which a surname/„Geschlechtsname“ was used before.
You may use the name Gottlieb as an assumption for further research, but unless there isn’t a proof (this one mentioning in the death-certificate is no proof), I would keep my research broader.
Good luck and kind regards from Germany
