I have a pending merger of Kendrick-720 and Kendrick-1189. This will require/enable the merger of several generations of ancestors. (The manager of Kendrick-1189 has not responded yet, but I understand the merger can proceed after 30 days). My concern is the ancestor mergers. These go back several generations. Moreover, the Kendrick-1189 tree goes back further than Kendrick-720. However, while some of "my" profiles are a bit sketchy in the "colonial" era, as far as I have looked the Kendrick-1189 profiles are all unsourced. I would appreciate comments/pointers on how to proceed.
