This is an old thread and I hope someone is still watching.
To export from Reunion 8.06 on a Mac to Ancestry, I created a GEDCOM and transferred it to Ancestry. No problems on the surface. My tree is intact. BUT my Note fields did not transfer nor did my Reunion sources. Note fields are very important to me. In the "old" days (1993) I was using PAF (Personal Ancestry File) from the Mormen Church. They had no sources implemented and recommended the sources (referencing our paper sources) be put in the Note Field. When I transferred from PAF to Reunion my Note fields and everything else made the transfer. Losing them on the way from Reunion to ancestry is bad news for me. The people at Ancestry were no help. Reunion has the note fields in their GEDCOM.
Has anyone found a work around to lost Note Fields?
