In my previous Blog<\/a>, I worked on updating the visual phasing for my late father-in-law and his two sisters. While doing this, I updated their DNA Painter Maps. I made an interesting discovery based on an old Cincinnati Butler descendant match that I had found back in 2015. The old spreadsheet that I had on Richard was helpful, so I updated that for him and one of his sisters. I will next update Virginia’s spreadsheet from Gedmatch.<\/p>\n

Chromosome 17<\/h2>\n

My note says that this is done but\u00a0 the paternal side needs to be idendified:<\/p>\n

\"\"<\/a><\/p>\n

On Chromosome 17, I was trying to figure out what DNA my wife inherited from her father based on the Chromosome Mapping.<\/p>\n

The key to Chromosome 17 is finding paternal matches. Not unlike the key to all the chromosomes. I’ll run Virginia against Jack, who is a top Kerivan match. I’ll look for the matches in common at Gedmatch and then run a Matching Segment Search. I come up with one match on Chromosome 17:<\/p>\n

\"\"<\/a><\/p>\n

It looks like Virginia’s paternal crossover is around 6. That would mean that paternal GP1 would be Kerivan. I see that Richard has a match with Jane also:<\/p>\n

\"\"<\/a><\/p>\n

I don’t see a DNA match between Jane and Lorraine.<\/p>\n

\"\"<\/a><\/p>\n

I’m ready to declare victory over Chromosome 17 and move on to the next battle.<\/p>\n

Chromosome 18<\/h2>\n

Assuming my previous work was correct, I first need to identify the easier maternal side:<\/p>\n

\"\"<\/a><\/p>\n

Next, I’ll add DNA Painter information:<\/p>\n

\"\"<\/a><\/p>\n

This works well, except for Richard’s purple match with Fortin\/Tremblay. Based on my visual phasing, there should be no crossovers in that purple area. My guess is that orange is LeFevre and that the purple match that Richard has with Gerry is not right.<\/p>\n

Here is Gerry’s tree at MyHeritage:<\/p>\n

\"\"<\/a><\/p>\n

MyHeritage was not able to figure out our common ancestor. I’m not sure how I came up with what I did. I would say now that it is not right or that there is a closer common ancestor. I decided to delete Gerry from Richard’s map until I can figure out how he belongs.<\/p>\n

The remaining question is the location of Virgina’s maternal crossover. That can be found at the Gedmatch full resolution image of the match between Richard and Virginia:<\/p>\n

 <\/p>\n

\"\"<\/a><\/p>\n

That happens here at about 42.5. That fits in with Virginia’s Lefevre match on Chromosome 18:<\/p>\n

\"\"<\/a><\/p>\n

Next, I need to find a paternal match to identify the paternal side of Chromosome 18.<\/p>\n

\"\"<\/a><\/p>\n

It appears that the salmon colored paternal side is predominately all Kerivan or all Butler. An in common match between Jack (who represents Kerivan) and Virginia didn’t show any matches on Chromosome 18. That means that I should run an in-common match for one of the Butler matches. Lorraine has a pretty good match with Kim at Gedmatch:<\/p>\n

\"\"<\/a><\/p>\n

I haven’t connected these two families by genealogy but they are connected by DNA and many circumstantial incidences. I had no luck finding Chromosome 18 matches with this comparison either.<\/p>\n

Chromosome 19<\/h2>\n

I’ll add the DNA Painter map to the bottom of the work I had done previously:<\/p>\n

\"\"<\/a><\/p>\n

It looks like Lorraine should have a maternal crossover where her match ends, but Richard’s Lefevre green is actually two matches:<\/p>\n

\"\"<\/a><\/p>\n

The problem is that I have not mapped Jane to Lorraine’s map. Mapping Jane onto Virginia’s map helps show Virginia’s Pouliot segment between the two Lefevre segments:<\/p>\n

\"\"<\/a><\/p>\n

It looks like there should be a crossover for Lorraine on the right side of her match with Jane. However, it appears that the match between Jane and Richard was larger previously. Now it is in line with the matches between Lorraine and Virginia:<\/p>\n

\"\"<\/a><\/p>\n

I guess the algorhythm changed at Gedmatch. I don’t feel like changing Richard’s results right now.<\/p>\n

A Paternal Match for Chromosome 19?<\/h3>\n

Using my previous in-common analyses, I have this Kerivan-type match for Lorraine:<\/p>\n

\"\"<\/a><\/p>\n

I have this Butler-type match – also for Lorraine:<\/p>\n

\"\"<\/a><\/p>\n

Unfortunately, that does not fit in with the way I have Lorraine mapped, unless I change the visual phasing. Due to uncertainties, I’ll leave Chromosome 19 for now.<\/p>\n

Chromosome 20<\/h2>\n

Here is what I had done previously for Chromosome 20:<\/p>\n

\"\"<\/a><\/p>\n

I’ll convert this to Excel from Powerpoint. I also want to look at the DNA Painter maps for these three siblings. Here is Lorraine:<\/p>\n

\"\"<\/a><\/p>\n

She has LeFevre DNA at the beginning and Kerivan DNA at the right end of Chromosome 20.\u00a0Lorraine’s matches appear to define Paternal GP1 as Kerivan.<\/p>\n

Virginia shows Pouliot up to position 60:<\/p>\n

\"\"<\/a><\/p>\n

Here is what Richard has:<\/p>\n

\"\"<\/a><\/p>\n

When I re-do this Chromosome, I’ll start from the righ hand side as the left-hand first crossover is not as important. I did this but got the same results:<\/p>\n

\"\"<\/a><\/p>\n

However, now I know the paternal side. At some time, I need to look at Virginia’s match list to see where her matches are falling out after position 60.<\/p>\n

Chromosome 21<\/h2>\n

Here is what I had done previously in Powerpoint:<\/p>\n

\"\"<\/a><\/p>\n

I’ll start by looking at the three DNA Painter maps. Only Richard has one match so far. That is for Pouliot between 10 and 22:<\/p>\n

\"\"<\/a><\/p>\n

When I bring this into Excel, I need to see the left-hand side:<\/p>\n

\"\"<\/a><\/p>\n

With the left side completed, I see the only color that Richard has uniquely there is blue, so that has to be Pouliot. That defines the maternal side of the three siblings’ Chromosome 21 and defines the maternal grandparents. However, it leaves a gap in Lorraine’s Chromosome 21.<\/p>\n

Chromosome 22<\/h2>\n

Here is the work I did previously:<\/p>\n

\"\"<\/a><\/p>\n

All l need to do is identify the two paternal grandparents. I checked the three DNA Painter maps and saw no paternal matches that would help me.<\/p>\n

Summary and Conclusions<\/h2>\n

My list of completed chromosomes is getting larger:<\/p>\n

\"\"<\/a><\/p>\n

I now have only 8 chromosomes that are not completed. If I do some more work on these, I may be able to complete one or two more.<\/p>\n
