I'm just wondering if mirror tree work is in disfavour.
I'm getting interesting results by attaching my spare DNA results into the family trees i have built for groups of my shared matches who obviously are all related to each other although i have no idea how they relate to me. The computer is doing a lot of the work of locating the common ancestors among the matches in the 'bucket'.
I label the DNA kit "Mirror Tree Work" and keep it private, of course. This hasn't caused a breakthrough yet, but it has led to a lot of clarity on exactly how the matches in each group are related to each other, even though of course some of the hints are obviously just plain wrong and others prove wrong upon further research. Combined with info from GEDmatch and FTDNA, there are enough seemingly valid hints that i feel like continuing with this methodology.
But is this practice frowned upon?
