I DO NOT link to burial UNKNOWN.
For body lost show me your proof.
If one is added to a cemetery and there is a burial unknown, body lost the unknown or lost will get merged to the one added to the cemetery first. Find a grave does not want doubles.
Simply having someone in your family tree is not grounds for a management transfer request.
I stay with Guild lines set by FIND A GRAVE for transfer.
That would be relatives within four generations. This would be your siblings, parents,your grandparents, Your great-grandparents,your children, your grandchildren, and your great-grandchildren.
NO BULK TRANSFERS.
I KEEP DATES THAT ARE ON THE STONE.
I do not add cut & paste census information.
