Military, Skåne, 1700's under Major A J Morman,

[Johnny Lindquist]

Where would I search for information to find out if a man served in the military or not or perhaps what area would he be serving in based on the following informatin?  A man born in Stiby presumably around 1690, married in Ekeby in 1724 and moved to Trånas in 1725.  It is my theory that he may have served under Major Anton John Morman or Colonel Rosencrantz.  I've seen his name as Olof Gundersson, Olaus Gunnars Lindqvist and Olof Gunnarsson Lindqvist
