I used the digitized sources that are avaiable from Arkiv Digital. I checked the church records where I though I might find the family, but didn't find anything other than the above from the english parish in Gothenburg. Unfortunately this parish lacks household examination rolls. There are also tax records (mantalslängder), but I didn't find the persons in the index. I might have missed them. The son was buried in Örgryte. Maybe that is a clue ...
