I agree with Jan in that if it's a true wool allergy you should avoid it altogether.
However, if it's simply a wool sensitivity certain varieties might not bother you. For example, shetland wool burns my eyes, makes me itch terribly, turns my skin red and activates my eczema. However, merino wool does not bother me in the least.
Peruse your local yarn shop to see. Also, I'd try a wool-silk or silk-cotton blend. Surely those materials were used in yarns circa 1861.
Best of luck!
