I have posted on the tree graphic and on the segment bar graph re: triangulation. I am a visual learner as are many people. That is what I start with so people can get used to the concept of triangulated groups and working with them. My focus is on what you see when you look at the tool. To "read" what it is telling you and how to respond to matches and get responses back. For the science behind the tools I always recommend reading Jim Bartlett's Segment-ology blog. Blaine T. Bettinger's books are very good. I am doing the posts as I can. Seriously, I DO blunder my way through. If I can succeed with all my blundering, anyone can. I just love sharing my successes and my failures. Let me know what you want to learn and I will do my best to blog what has worked for me.<br />Anonymoushttps://www.blogger.com/profile/02363894229704326222noreply@blogger.comtag:blogger.com,1999:blog-2043962637817278377.post-55737627151175412092017-05-10T14:42:19.258-07:002017-05-10T14:42:19.258-07:00GizCat, you could also do triangulation and see wh...GizCat, you could also do triangulation and see who you link to and capture their trees.

Eventually you will find several of your closest matches showing up as their closest matches. That will assist you in sorting your lines, your maternal and your paternal. (unless they are related) If you do a bunch you will actually find at least four lines. A's maternal and paternal and B's maternal and paternal. It pretty much depends on how close your matches are. You should end up with at least four distinct groups.Anonymoushttps://www.blogger.com/profile/02363894229704326222noreply@blogger.comtag:blogger.com,1999:blog-2043962637817278377.post-27867999887412041772017-04-29T21:58:16.304-07:002017-04-29T21:58:16.304-07:00I am so sorry I didn't see this earlier; I am ...I am so sorry I didn't see this earlier; I am not exactly a computer genius and thought I had this set up to notify me when I received a message. April, it means you probably only match on one name and they don't share DNA with the others. Or they don't have that cousin in their tree. Remember you have two genealogy trees one is paper, the other is a genetic tree. Not all cousins share DNA. I would highly recommend you donate $10 one time to use Gedmatch Tier 1 and download from their triangulation program into a spreadsheet. I will be covering that info in the coming weeks to explain it to everyone. If you have the surname Brady anywhere in your tree, I am doing a triangulation and segment study on that surname. PM me on FB if you do.Anonymoushttps://www.blogger.com/profile/02363894229704326222noreply@blogger.comtag:blogger.com,1999:blog-2043962637817278377.post-77186505946610120042017-04-13T15:17:22.324-07:002017-04-13T15:17:22.324-07:00Am I correct in assuming I should only compare my ...Am I correct in assuming I should only compare my closest match with their 4 closest matches.

I attempted my first matrix, however I only had 2 other shared matches from a 4th-6th cousin to work with. One of the shared matches has NO surnames common to all/any 3 of them - I was wondering what this might indicates? I was surprised as they have over 500 names in their tree.

Col. B you begin with SHARED matches of your closest match. I would do several entries for their closest SHARED matches and keep adding to this page until you get repeats of the same surnames. Eventually you will come up with the same given and surname with correct locations and birthdates (I allow a 2 year play one birthdates because so many people estimate from census records. <br /><br />After you find common ancestor for your closest matches matches. Do the same thing with your second closest matches shared matches. By the time you have done this for your top 15 closest matches shared matches. you should have at least a few for your different parents. Much depends on how close all your closest matches are.<br /><br />When you are certain (you have made notes on your maternal line) then go ahead and do the closest matches shared matches. Don't be surprised if you discover they are from your maternal line, only further back. I spent 3 weeks sure I was working with an adoptees bio father's line; turned out to be her mother's. Bummer. But I was able to build her maternal line much further back in the process.Anonymoushttps://www.blogger.com/profile/02363894229704326222noreply@blogger.comtag:blogger.com,1999:blog-2043962637817278377.post-43918689232313710272017-04-03T22:36:06.350-07:002017-04-03T22:36:06.350-07:00GizaCat, I do this to breakdown brickwalls.

See if you come up with a common surname in their tree and use it (if they appear to link to your grandmothers) use that surname and study it carefully. Look at other people's tree with surnames for your grandmothers. Many people used their middle name or nickname which can throw your genealogical research off. Pay close attention to dates and locations. See if you can find siblings for your grandmothers. Look for people born within one or two years of their birthdates in the same geographical area. Sometimes parents died and grandparents raised the children. That might have happened with your grandmothers. Depending on the time, some parents sent their children to live with relatives before the Civil War broke out. That may be a reason you are having challenges finding their parents. I would also recommend doing Gedmatch Triangulation and segment comparison. Perhaps they will show up there.Anonymoushttps://www.blogger.com/profile/02363894229704326222noreply@blogger.comtag:blogger.com,1999:blog-2043962637817278377.post-76228460144947139742017-04-02T12:55:42.211-07:002017-04-02T12:55:42.211-07:00What do I put in the B Column?
