Nicole,
Thanks again for your help. Unfortunately I don't know who any of James REDMANs son's married. I only know their names and dates of birth from the 1850 and 1860 census. I would try to track them in later census but I no longer have a subscription to census data.
If you can find anything on them or Sarah REDMAN would be a step more than I have now.
Best Regards,
Brad
