Kelly, When a mutation appears in only one individual within a set, we cannot attach much meaning to it. It is only when others in the set start showing up with that mutation that we can look for possible connections. There are a few markers that seem to have many parallel mutations, most notably the CDY complex (markers 34 & 35). A mutation at these markers does not necessarily mean a closer relationship to others who have the mutation but should be kept in mind when looking for connections. Marker 30 is suppose to be a site that mutates more quickly than other sites though so far this doesn't show up in the Kincaid project. There is one other Group A-1a Kincaid who has a 16 at marker 30 (DYS456). The value of 18 for A-2b and 25710 are the only other incidence (besides your line) of mutation at this marker in Group A. 25710 claims descent from Joseph/ Eliz Gray Downing who was born in 1771. The family moved from KY to Crawford Co. IN. Your Mathew Kincaid indicates in the 1850 census that he was b 1807/8 in VA. I don't know whether Joseph's researcher knows when Joseph or his family moved to KY or where he was born (Boone didn't lead the first settlers into KY until 1775) so it is possible that somewhere there could be a connection. However, if your Mathew is proven to be the son of Francis, son of Thomas/Hannah Tincher and Joseph can be vetted as ancestor of 25710, it looks like the 2 mutations to 16 were parallel as the others who have potential to Thomas/Hannah do not have that mutation. Still you do have to keep the 25710's matching mutation in mind and should, along with the researcher for 25710, eliminate any possibility of connection.
