I also descend from James Jagger b. Apr. 9, 1843 in Halifax, W. Yorkshire. My grandmother was Edna Una Jagger Muffley, sister of William Hardy Jagger. James Jagger & sibs were orphaned early. Brother Tom was lost at sea, brother Jack ran a hotel in Blackpool, sister Anne married a Bolton, brother William settled in Penn. James Jagger's first wife Jane Little died in childbirth. Second wife Frances Weidenhamer had Glenn ancestry. James Jagger lived in Adams Co. & Knox Co. Illinois. Weidenhamer & Jagger families were big time into railroading, which accounts for the Colorado connection. I have much data & family photos. Contact me please.
