I am researching McGinnis/Callahan from Blackstone MA 1850-1920's. Most of the McGinnis's moved to Minnesota in 1860's but some remained behind and married into the Callahan line. I am from St. Paul Minnesota but currently live in Omaha NE. Would the researcher who offerered to do some Blackstone library lookups for me please contact me again as my PC crashed and I lost your email addresss. Thanks Tom Gerber
