I have another daughter for Mary KILKER CASEY: Susan. Her husband's family name is SCHENK and their son's name is Tom. This branch could very well be yours! I have no other information about Mary KILKER CASEY. ¶As you have a time-linked lead (1897) to Chicago, have you tried to obtain Mary's death certificate? This may give information about her parents. ¶Other possibilities are to go on the CASEY and SCHENK forums (if any) and ask for leads. The 'Irish' trunk of the KILKERfamily tree does seem to be blooming in County Mayo, Ireland. (There is a 'German' trunk, also; for word of this see the work of Karen KILKER BROWN in this forum.) ¶I've had little success with organized search services in or about County Mayo and much more success with family and personal contacts. There are also several published books that mention KILKERs in Mayo and nearby. ¶I suggest you reach me off-line and we can continue discussing this.
