To follow up the earlier answer to Marc, here is the on-topic paragraph from the
Rice site. Go there:
http://www.widomaker.com/~gwk/era/haplotype.htm
for other informative links. Apparently, we seek to recontruct the: 'genetic
"fingerprint" or haplotype of our immigrant ancestor.'
The Edmund Rice (1638) Association has a project underway seeking to discover
the ancestors of Edmund Rice and other Rice and Royce families. (There was a
tendency in past centuries to regard these two spellings as interchangeable.)
Y-chromosome DNA analysis offers exciting opportunities to learn more about
early family roots. With the assistance of three genetics testing labs, we
compared the DNA of many descendants of Edmund Rice of Sudbury and Marlborough
and reconstructed the genetic "fingerprint" or haplotype of our immigrant
ancestor (see Table 1). For the details of how we did this, see the article
entitled "How We Obtained the Rice Haplotype" in our newsletter.

| Hi Marc, Good Questions:
|
| [Q: Does it matter if you have descended via mothers or fathers? Does your
| pedigree from Robert Witherington have to be all mothers or all fathers or can
| it be a mixture?]
|
| Been awhile.
|
| Getting dna is a medical exercise. But finding common dna establishes
common
| ancestors OR lack of common dna establishes lack of common ancestors. So we
| apparently assume that if 10 Wtons are tested and 9 have the 'common' dna
| traits, then the 10th one is from another line. If we had Robt's dna, we could
| determine exactly if anyone was a descendant of Robt. Even the Mitachondrial
| (sp?) dna directly from the UK mummy found in ice allowed establishment of an
| exact descendant after 5,000 yrs.
|
| Each descendant carries half the dna from each parent. There are different
| kinds of dna - some more useful for female linkage - other better for male
| linkage.
|
| If I'm from Robt, then your dna must match mine in relevant detail. If we
| attempt to match just 2 people, then all we know is whether we are in the same
| or related Line, or not - not which line until we get more samples. And I'm
way
| above my head now.
|
| The Rice dna stuff should answer many ques.

| | I'm a little bit confused. Maybe you can answer these two questions:
| |
| | How do you get DNA for Robert Witherington?
| |
| | Does it matter if you have descended via mothers or fathers. Does your
| | pedigree from Robert Witherington have to be all mothers or all fathers or
| | can it be a mixture?
| |
| | Thanks.
