Elizabeth, you may want to look  online at International Society of Genetic Genealogy. http://www.isogg.org/    They have some nice tutorials.  You mentioned your haplogroup. I assume you got  that from your dad's DNA?  There are several companies that do DNA testing,  What company did you use?    Now I'm intrigued too.  As far as I know,  my maternal line I can trace back to Jane who married John Benney--their child Jenifer was my 6xgreatgrandmother, baptised 1765 in Colan, Cornwall.   I've seen some Y DNA testing for some Cornish families, but not much on the maternal lines...   Julia Hanneman-Schoenbach, Waterford(nw Detroit)  MI USA  main families Jacka, Penhaligon, Toy   ________________________________
