This was really difficult. The only thing I can add is that they probably also are found in Göteborgs Karl Johan (O) AI:3 (1835-1836) Bild 39 / sid 73 (AID: v35079.b39.s73, NAD: SE/GLA/13186). Although some data are different it must be the same persons. But I don't find anything about them in Domkyrkoförsamlingen, and not even Carl Mauritz born 1837, which should be in Karl Johan, as they lived there at that time.
Hi Leif,
I think I found the Bernhard Julius that you referenced above (please see the image). Is there is a chance that you might be able to read what is written to the left of his name and tell me what it says? All I can make out is that he was born on May 17, 1835 and baptised on May 18, 1835. I might even have these dates wrong as it seems to that baptising a baby the day after he is born is very quick!?
