Finding the Sisters of my Direct Lines for Clues to DNA Connections

Following my own advice and working on the daughter lines of my GGGG Grandparents.(eventually I will do this for my 5th greats)  Had so many names not in my direct line among those with a large portion of DNA matching close enough to put us as connected around the GGG or GGGG and started noticing surnames that were repeating.  So now I am going in search of those names.  Have already found where a sister of my Frizzell married into the Elliot family.  That may be the reason for several occurrences of the Elliott surname in a few of my matches files.  This is not an easy process.  DNA by itself is meaningless if you can't find the connection and back it with a paper trail.  It's not like the DNA linking someone to a crime where you have the  crime.  So now I think I have about 20 specific DNA projects I am working on to find cousins.....and then there are the other priorities in my life which come first.  I so wish I was more organized but I guess that is something for which we all strive.
