I provide the following DNA and genetic genealogy services
Analysis of DNA test results to whatever level is needed to meet your research goals. More details are provided below.
- Recommendation for
DNA tests needed to achieve your research goals.

For these DNA-related services I need the following items:
- Your specific research goal (determine the probability that two persons are descendants of a common ancestor and within what timeframe, determine whether
two female lines might be related, etc.).
- A detailed descendant chart from the probable common ancestor
to the descendants of interest for this goal.
- For autosomal DNA analysis, a detailed pedigree chart showing all known ancestors. The more robust and complete the pedigree chart is, the better chance there is of fidning a common ancestor.
- All pertinent information about the person(s) targeted by
the request (documents and sources that help prove the family links).
- Any additional information you may have that could make the research more specific and efficient, such as family group sheets, pedigree charts, family legends and stories.
For direct paternal line (Y-DNA) testing
, analysis may include comparing your DNA data to those with close matches to assist in determining likely family groups. Factors taken into consideration include the number of markers tested, whether any differences are on fast changing markers, whether the family group displays more mutations than statistical averages, and how the mutations correlate to the lineage to support or refute hypothetical relationships.
For direct maternal line (mtDNA, mitochondrial DNA) testing
, analysis may include comparing your DNA data to those with close matches to assist in determining likely relationships. A full mitochondrial sequence is more useful for genealogical purposes, but mtDNA matches may be much further back in time than Y-DNA matches. There are specific situations where mtDNA is the best evidence and some situations where a lower resolution test than the full sequence can help. Analysis of the research goal can determine which test may help. A full mtDNA sequence can reveal rare mutations that can link families in a genealogical time frame, but may reveal implications for medical conditions. For this reason an analysis of the full sequence for possible medical indications should be done before sharing the mtDNA data with others or contributing the DNA sequence for scientific research.
For autosomal DNA (atDNA) testing
, which can indicate relationships on all of your lines, analysis may include comparisons of the matching DNA to determine likely relationships, conversions between shared percentage of DNA and other numerical results (such as CentiMorgans and longest blocks) to allow comparisons between different testing companies, and chromosome mapping to determine which ancestor particular blocks of DNA have been inherited from. These techniques are useful for traditional genealogical research as well as searches in case of adoption and other situations where the biological parent is unknown.
The costs will be charged as follows: hourly research fee
including time for accessing test results on a company or third-party website, research, analysis, and report preparation, PLUS cost of photocopies, long distance phone charges, postage and handling, travel, and other ordered or approved out-of-pocket expenses. Balance in full is due before the final report will be sent. Refund of unused deposit fee, if any, will be sent along with the final report.
What You Should Do
After you determine my services meet your needs and have gathered the information I need from you in order to perform the service, e-mail your request (using the "Contact" information at the bottom of the page).
Include a telephone number if you wish to discuss your
request via a phone call. This initial contact should include
a list of information you have that is pertinent to your request
but need not include photocopies at this time. Include
information that may
have an impact on estimating the scope and/or amount of time
involved to complete your request.
After reviewing your request, I will contact you with
an estimate of the time needed to complete your request, how
soon I can start on your request, and the hourly fee. If I feel I cannot provide
you with the service requested I will try to refer you to another genealogist.
If you decide to engage my services you can send
a deposit and authorization letter of the terms of our agreement
and I will begin work on your request.
Links below access authorization letters that can be printed,
filled in and mailed with your deposit check or money order. A printed and signed authorization form is required before work will begin.
