You didn't specify what kind of DNA test you did; there is more than one.
However, from the number of "matches" (1240) I'm going to guess that
autosomal DNA. This number of matches is fairly common with atDNA.
If so, don't worry about the "50 or 65 generations". The atD\NA matching is
basically limited to five, maybe six or seven, generations of separation.
Beyond that, the genetic signal gets swamped by background noise.
Nor, did you say which company you tested with; it could make a difference.
The "Big Three" in the field are Family Tree DNA, Ancestry DNA and 23andMe;
these are reputable companies with databases suifficiently large to yield
If you want to follow up on some of those 1240, I'd suggest looking at the
size of total DNA shared and the largest single shared blocks. In general,
the larger the block (& the total) the closer the relationship.
The four standard types of genealogical DNA tests are
1. yDNA STR -- for direct paternal lineages up to ~24 generations (roughly
the time of universal surnames) and for males only.
2. yDNA SNP -- for ancient patrilines, generally beyond 24 generations
(exceptions exist) also males only
3. mtDNA -- for tracing direct maternal lineages, many generations but more
ambiguous,, both genders.
4. atDNA -- for indirect relationships out to about 4 generations, both
There are other, non-standard tests. But it's generally recommended to use
them only in conjunction with the standard tests.
Incidentally, I'm the administrator of a large DNA project for a common
surname. I have to know this stuff.

Subject: [LAN] Looking for advice about DNA matches
Content-Type: text/plain; charset="UTF-8"
Hello Fellow Listers,
I feel very fortunate to be able to trace my line in Lancashire back 10
generations. Recently, I had my DNA tested and I'm now getting email
messages talking about individuals with matching DNA to mine. Apparently, I
currently have 1240 matches, most of which are with 50 or 65 generations,
too many generations?for my tiny mind to deal with.
I'm at a loss as to what I should or could be doing with this information. I
thought of building a spreadsheet with 1240 entries to see what pops up; of
emailing some of the matches within more recent generations to ask if their
lines went through Deane Parish or other Lancashire locales my people lived
Acknowledging that I must not be the first lister to find himself in this
quandary, I would like to petition for advice as to how other listers have
dealt with this new information. No idea is too strange or too far outside
Thanking you in advance,Norm Ashton(logging in from Toronto, Canada and
going through life like a porcupine in a room full of balloons!)
