NEW: Surname Search – More Investigative Leads
While forensic genealogy provides new data for solving cold cases, not every DNA investigation generates investigative leads, especially when usable sample is extremely small.
Bode’s genealogy team and partners implement advanced genealogy techniques in our Surname Search service utilizing a Y-chromosome profile to perform advanced searches on available Y DNA kits.
These searches can develop inclusive and exclusive information on biogeographical indicators, and may develop potential surnames linked to the unknown evidence. The Surname Search is executed in three phases.

Bode offers this service for DNA samples as follows.
- Forensic Y-STR Testing: Searches are performed on traditionally tested forensic Y STR samples.
- Genome Sequencing: Y STR information is extracted from genome sequenced samples.
- Expanded Y-STR testing: Extracted DNA may be searched against available surname databases.
If needed, additional evidence extractions can be performed in our ISO17025 accredited laboratory.
Haplogroup and possible biographical origin research
The resulting Y-DNA profile is analyzed to determine the unknown sample’s male biogeographical origin and Y haplogroup. This has significant benefits to identifying a suspect or the identity of remains by providing:
- More information to investigators as they evaluate their cases.
- New information for our genealogists to help advance relationship investigations.
- Evaluation of the likelihood of developing a surname for the unknown evidence.
Y-STR comparison to surname sources
When the surname search advances past the haplogroup determination, Bode’s team will search the Y-DNA profile against online data. The investigative goal is to develop a single surname or a limited list of potential surnames associated with the unknown evidence.
Bode works with agencies on a case-by-case basis to perform testing on samples containing multiple profiles. Samples are evaluated on a case by case basis to determine the chance of success, which depends on factors such as the ratio of each DNA profile in the mixture, the amount of DNA available, and the availability of a known sample.
