I started years ago in ancestry.com to create a tree based on 1) a DNA TEST at ftdna.com that showed my undiscovered Jewish ancestry (origin Lithuania) and 2) my visits to meet two parts of one family who lived near both coasts of the USA. The younger of the three DNA cousins I met gave me access to her tree, so I could follow the trails. My missing paternal GF might be in there.
I added members she didn't have and omitted many, always checking with her. Ultimately I ran a Gedcom and began cutting out those who did not belong. Now I'm ending the second hiatus from working on it, about to expire (not sure). The easy part of this is first, is my gedcom use still active, i.e., does it exist? and Where is it, i.e., How do I get back to my gedcom check to eliminate the "extras"?
But: I pushed a wrong set of computer keys on leaving this gedcom the second time and it suddenly and automatically added many people I've never heard of. How do I eliminate them?
And: How do I connect my Jewish tree to my English, AmericanPioneer, Scottish and German tree or do I just place it separately as a new WT tree, with explanations in the biography? Do I just junk the gedcom and transfer my Jewish family one member at a time, using "Unknown Unnamed" for his place holder?
And: I'm 79 and my memory slowly gets worse. (This man is my_first_paternal_GF_(UNKNOWN_First_Name_and_surname)
