Related to the Porsgrunn link... I have seen this area in a couple of contexts. I know it is adjacent to my ancestors home in the Bamble and Brevik (Brevig) area in Telemark. I found some very useful links by a lady named Kirstie Sorter, who lives in that area. She has listed the cemetaries in that area for Brevik and , I recall, Porsgrunn and Gjerpen The link I had for this is http://home.online.no/~sorter/kirkeg/kirkegaard.html now. http://www.porsgrunn.kommune.no/ may be another link. I also recall some Porsgrunn names in the Hainesville Cemetary in Door County, WI. Maybe some links for you there too.
