One of the two key processes to working with your DNA matches is to determine the relationship between you and each of your Matches. As you work to determine that relationship, start by evaluating your matches. Review the name of the match and the manager of the DNA kit. Identify what the generational relationship you may be to the match by comparing ages (the Match as well as their parents or grandparents). Review the Shared cMs Project to determine what potential relationships that amount of DNA may suggest. And consider what clusters the match already belongs to. Evaluating the match ahead of time will give a sense of where in your tree to search for a common ancestor. | One of the two key processes to working with your DNA matches is to determine the relationship between you and each of your Matches.

The process for determining a relationship is as follows. | |||
# Start by choosing a match. Evaluate the match. | |||
# Review the family tree of the match. If the tree is incomplete, you may have to build out their tree or contact the match for more information. | |||
# Identify the most recent common ancestor or MRCA. Remember that you will need to be familiar with your own family tree in order to spot the MRCA. | |||
# Determine your relationship to the match. It may be helpful to draw it out in a descendancy chart. | |||
# Record the relationship using the notes feature of the DNA website or on a separate spreadsheet or file. | |||

For maximum results, seriously consider testing with every company. You never know which company will list the closest match that can solve the problem. | For maximum results, seriously consider testing with every company.
