I need to know the membership of churches in gaffney sc from 1993 to 2002

Hello--
Since Baptist churches have different affiliations (Southern Baptist,
for example), or none at all, depending on the church, you would need
to check with each individual church.  In the South, Baptist churches
are very common and diverse.  It appears from
http://www.hamptoninngaffney.com/info.htm that Gaffney has at least 20
Baptist churches right now.  Over the years, some may have come and
gone, complicating the research. Good luck!
