Hallo Pat. Like yourself, I have not been researching for a couple of years because of personal circumstances. But I do recollect that you and I have shared information previously. Looking at this from the perspective of a computing systems professional, it seems at first glance that some sort of processing error has occurred here, rather than that someone has tried to steal your tree. Possibly someone copying across your data en bloc and then deleting all the surplus that did not apply to their own lines. And then, perhaps, accidentally storing the "new" tree over your existing tree rather than to a new file. The system should not, obviously, allow this, so there would have to have been a bug in the software (or a fault in the software design). > It took me all afternoon to replace my parents and family Have a care here! You don't want to get into some sort of conflict with another researcher, both claiming ownership of the same tree and continually overwriting each other's updates. I can see that this is vexing for you, but it seems to me that your best plan is to try to identify this other person and then open a conversation in an amicable fashion. It is clearly in both your interests, given that you have common ancestry, to try to proceed in a co-operative fashion. Regards, Ron Snape (and all the best for the New Year!).
