Hello Patricia,
You can learn more about your Richmond ancestry if you register at gedmatch.com and follow their directions to upload your AncestryDNA results there. Some of your DNA matches may have information about Miranda’s ancestry that you don’t yet have.
Then add your GEDmatch ID to your DNA Tests page in WikiTree at HTTPs://www.wikitree.com/wiki/Special:DNATests .
After a couple of days you will be to see your relatives in WikiTree who tested with AncestryDNA, 23andMe, Living DNA, MyHeritageDNA, and Family Tree DNA’s Family Finder. See: https://m.youtube.com/watch?v=1NgD9b3s0Gs
