English - Swedish ancestry

[Colin Rowledge]

I have a chap who was born in England as a result of a marriage between a Swedish mariner and a Cornish girl. Their son eventually in 1901 served 1 year for bigamy. Before his conviction,this chap,fathered, through another Cornish girl, a daughter who married into my mother's family.

How do I find information from Sweden about the grandparents and family of the bigamist?

The family name was AHLSTEDT

Thanks

PS - can we fix the heading - I missed the 'h' in English?

Hi Colin,

Title fixed.

Have a look at this thread (http://www.british-genealogy.com/forums/showthread.php?57434-Swedish-Ancestors-migration-records&highlight=sweden). It may provide some tips.
