Swedish Military during 1600's

[Robin Honel]

Hi!
I am interested in a Baron Carl von Honl who was a Captain for the Swedish Army during the 30 years War in Czechoslovakia - 1618.
Is there any way to find military records for these years.
Are there any Honl families still in Sweden?
Does his name-Baron indicate Nobility and where would I search for this?
Any help would be greatly appreciated!
Thanking in advance,  Robin Honel
