Death CD Look up Please for Nyqvist

[Michael Newquist]

I am looking for some help in trying to locate death information on a few of my family.
 
Henrik Nyqvist
Born: 05 Mar 1798 in Älgå
Married: 01 Jan 1835 in Stavnäs to Kerstin Andersdotter Sundstrom
 
and for:
 
Kerstin Andersdotter Sundstrom
Born: 24 Apr 1796 in Sunne
Married: 01 Jan 1835 in Stavnäs to Henrik Nyqvist
 
I am not sure when either one of them died but it had to be sometime after 1840.  They had at least 3 children:
 
Johan Nyqvist b: 31 Jul 1835 in Stavnäs parish, Vermland county (former Carlstad county).
 
Anna Catarina Nyqvist b: 24 Feb 1837 in Stavnäs parish, Vermland county (former Carlstad county).
 
Thure Nyqvist b: 05 Apr 1840 in Råneå, Norrbotten.
 
I thanks for the help.  Please email me at mikeylikesit89@msn.com with any information.
