Sorry for the delay in getting back to you but I have been traveling most of this year and have not had much time for the Internet. I may have written to you in the past when I was actively involved in family research but that was put on hold about a year ago for business reasons.
You might want to contact a couple of people who have posted messages on this site, Judy Garvin and Jeff Kranig they may be able to assist you in your search. Both Jeff and Judy are good people and have gathered an abundance of Kranig family information.
P.S. I have just read some of the postings on this page regarding a Jeff Kranig. Just for the record, the only Jeff Kranig I know from the Chicago area is my cousin Jeff and he is totally honest, trustworthy and certainly “No” Internet hacker. Please do not be concerned about sharing information or correspondence with Jeff as any material or conversations will remain private and confidential.
