Oliver Cromwell's army - is there a list of officers and soldiers?

[usaPetticrew]

Does anyone know of an online resource with a list of who served in Cromwell's army?

This would have been during the English Civil War, 1642-46.

I am specifically interested in finding a James Petigru or Pettigrew, or some variant thereof. 

Family lore says James served as an officer in Cromwell's army.  Whether he served as an Englishman, a Scot, or other, I don't know. 

"A Scottish army crossed the Tweed in January 1644 at the behest of the English parliament and, for the next three years, Scots and English would fight alongside one another as allies. "

Thanks for any help you can offer.
