Williamson/Ball lineage

I have been researching my Williamson line for 30+ years and still have a descent memory.I have come across many articles concerning Rev James Williamson and his wife, Ann Underwood and Rev Alexander Williamson and his wife, Ann Hynson.There is much information regarding their ministry in Calvert and Cecil County, Maryland.I remember finding many times Margaret Williamson marrying a Ball however at this time don't remember his first name.I believe she was the daughter of one of the above however since this is not my direct line,I didn't pursue further.Their are many records which state that he was a "kinsman" of my ancestor, John Williamson, h/o Jane Pringle however I have not found any connection yet.If you have trouble locating any of this information, I would be glad to offer my assistance.For anyone not living in the Maryland area, I will be going to Maryland hopefully within the next few months.My email is [email protected] Fink
