I too have Belmont County, Ohio Quaker ancestors who came from Pennsylvania.
The Revolutionary War caused much emotional trauma in Quaker families when some 'took up arms' and therefore were not welcome in the faith anymore since that was not following the Quaker's peaceful ways. Some married a person out of the Quaker faith and that was reason for them to be 'shunned' and no longer welcomed in the group. Others followed their families who moved away from Quaker surroundings.
Many of the Quaker Meeting records are available online - but not all.
When my family moved from Pennsylvania to Virginia, family stories passed down tell us of this 'trying time.' My Pennsylvania Quaker families 'took up arms' to defend their new country.
After the war, they moved into Ohio wanting land for their family and while they tried to continue living within their Quaker faith and may have done so for some time, however, moving into larger parcels having smaller communities, they found fewer 'like minded' people living near them. Since attending church was important to them they found a church of a 'similar' faith closer by and they attended that one - becoming members. Families attended church - first and foremost - whichever church was available. Church was the center of the community - whichever denomination it happened to be.
Following the flow of our ancestors over time by church affiliation becomes very interesting as churches influenced many family behaviors.
