Greetings from a new member: Seeking information from Ockelbo, Gälveborg.

I am interested in any substitute information from Ockelbo, Gälveborg, Sweden.  A fire there in 1904 destroyed the Parish records.  Specifically I am interested in Olaf (Olie) JOHNSTON (b. 1823 probably at Norrbo, Ockelbo) ancestors and those of his wife Marta or Martha (father's name unknown, b. 1824 Possibly in Ockelbo).
