It may be possible to confirm family relationships with Verlinda by comparing test results with other carriers of her mitochondrial DNA.
However, there are no known mtDNA test-takers in her direct maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Verlinda:
We both agree that Magruder is the correct LNAB. McGruder-77 should be merged into Magruder-158 with McGruder-158 being the New profile. I thought that's what I set up, but I'll let you do it this time!
Magruder-24 and Magruder-61 appear to represent the same person because: There seems to be some question as to the mother of Verlinda and the wife(s) of Samuel Magruder Sr. These need to be investigated through the sources so as to come to some facts as this is an important part of two family trees.
