Maybe I should have been a detective!
Since retiring from teaching eight years ago, I have started to organize my family history research more carefully. This is mainly because of the DNA tests I have requested from members of my family. I am having to keep better records of what I have done and who are matches to all the people I have had tested. Thanks to UTAS for the Diploma of Family History which I have completed since retirement. They helped with the organizing and planning for my research.
At the moment I am working with an as yet unknown 4th cousin with username wollen100. She matches my mother, my brother and me with DNA . It is only a small amount about 21cMs for each of us. But we think it might come down through the BOYD side of the tree.
Me, daughter of my mother, daughter of Hannah DAVEY, daughter of Martha COLGRAVE, daughter of Susan BOYD, daughter of John Henry or Holliday BOYD and Martha BOYD , was Virco/Vico nee HEARN.

On two birth certificates for John’s children he is mentioned as John Holliday Boyd. Looking on Ancestry, most public trees have his parents as William and Ann Boyd from Ireland. But I think that name Holliday must be significant. Also I noted that John had no children with the name of William. Perhaps a clue that William is not his father.
John was a convict tried at the Central Criminal Court in London and sent to Van Diemens Land (Tasmania) in the 1830s. But on the convict conduct record it says his native place was Plymouth which is in Devon in England. I have found a John Holliday Boyd born in 1809 in Maker, Cornwall which is across the river from Plymouth. Parents were Robert Boyd and Nancy Holliday and their marriage was in 1797 in Devon. Maybe these are the couple I need to concentrate on to find that connection to my 4th cousin.
She has a lot of ancestors in the Plymouth area of Devon with surnames VEALE, WYATT, ELLIOTT, PRIDEUX, WEST, SWAIN and WICKETT. So more research needed to connect my Boyds to one of these names on my cousins tree. I have found an Ann Boyd marrying a Richard Wyatt in 1793 at Ivybridge in Devon. Maybe Ann and Robert are siblings!
Come on Sue, get on with that research!!
