Rev. James Anderson -- may be a different one that wrote the Masonic Constitution

Not a clue. I set up my family tree and a few people asked me if they could merge the information they gathered and the next thing I knew I was related to Ceasar and The Queen Mother became my 13th cousin. Be careful who you let merge and with whom you merge. Best info I can give you.

Thank you, John! I actually already had a similar experience -- Ancestry.com had the wrong parents for one of my great grandmothers and once I merged them with other profiles here, I was supposedly related to a Salem witch and Charlemagne. A kind curator helped me out of the mess, but since then, I am being extra careful to check, double check and triple check my sources.

In fact, after doing some more research yesterday, not only do I think that these are two different James Andersons, I think that they are linked to the wrong descendants. I found fairly accurate information up until my 7th great grandfather, John Anderson (c. 1704-1756), but beyond him, everything gets a bit blurry. It seems pretty certain though that he was born in Ireland, which would mean that not only is it unlikely that the London James Anderson is his father, but the PA minister couldn't have been either.

The search continues and good luck with yours!
