I have recently received markers 25-37 and really do not know how to interpret the values. From reading the threads from this group, it appears that there are a number of "experts" on the topic. Can anyone tell what all these markers mean, aside from the fact that two people with the same DNA are related somewhere back in time? Do some of these markers identify the location from which the "family" originated? If one does not have an exact match, which markers are the most important to suggest a strong connection? To the contrary, which markers must match to assure a connection?

Another Grant and I had a 25/25 match, with a 50% probability of having a connection within 7 generations. Now we have 37 markers and a genetic distance of 3 and a 50% probability of a connection within 19 generations....I don't understand this! Locus 30, 32 & 36 are different by 1.

Below are the markers:
