1) You might be able to take the grdcom file to some place like a Office Depot and have them print it for you. Also it might just depend on you tree program. There are lots of charts and reports available with PAF but don't think it works on a Mac. You might try searching the web.
2) It says you are interested in the Hart family of County Armagh around 1800 os so. Is this right? If so I am intersted in a Isaac Hart born in Armagh ca 1780.
