have been working on Creagan/Cregan/Cragan files for abt 7 years. I have a pretty comprehensive tree but there are still alot of unrelated creagans in there I just submitted to FTW and posted it on a geneology.com home page (family files of Creagan's) If you cant find I would be happy to send to you.
Your Cragan interests me becauseI have8 unknown Creagans from the same time frame that you are writing about. Brother? Patrick Francis Creagan b. 1836 (NY) d. 1895 (MO). Any additional info would be great .
