Hi Sande, there is BURGE families in NC of which maybe your Sidney is part of the family. You have to look at the many variations of the surname and I suppose when she moved to Illinois they started to spell the name Birge since there were Birge in Illinois. But then again some spelled it Burge also in Illinois. Just depends on the person writing down the information. Reason for soundex. I'm still trying to figure out a William Birge (might be tied into the Burge line in VA/NC/TN. That line ended up with the surname spelled BIRGE also. The Kentucky BIRGE line came out of Tennessee and assume from VA/KY and might have been from a line of BURGE/BURDGE or BURGESS out of NY in the 1600's. I have yet to find any of the Connecticut BIRGE's that would tie to the line. I have found a couple of brother's that went south to South Carolina & Georgia and one brother's descendants ended up in Texas. I'll watch for Sidney.
