Images of my DNA focus.
PYCROFT Family of 1825

This is a McGUIRE chart.

This is a McGUIRE chart. The relationship boxes were created by TWO [2] screen-shots of 2 BROTHERS KEEPER dsisplays and pasted together onto an XL Spreadsheet. The COUSIN lines and AUTOSOMAL cM Values added to complete the 'picture'. - | - See the large range of cM for the 3c-1r relationship. See descendants of two brothers (Y-DNA) and a sister - siblings of our MDKA is also our collective MRCA. [Most Recent Common Ancestor]

I have paid for the FIVE Y-700 DNA tests shown here. See that my Uncle Stanley and myself are identical. -- | -- However, initially Stan's 2nd Cousin was different. I was fortunate in that there was a 4th cousin who agreed to test. As shown here, he completed the alternate haplogroup. -- | -- He, along with Reginald were R-FGC65746 while Stan & me were R-BY76765. The 4th cousin test permitted the identification of another Haplogroup, and so R-BY44310 split off from R-FGC65746. I needed to determine how different Reg was from Stan & me and my 2nd agreed to test. (Thank you.) The upshot of that is that KD [SPLIT] our haplogroup alolocations and added another branch - by virtue of age of MRCA (Most Recent Common Ancestor). That has taken me on quite an analysis journey with figuring out the nature of passage of mutation (SNPs) between a father and two sons. I do not think that I will be able to determine exactly the happenings, however, all the indicators are in the same 'ball-park' so to speak & is acceptable. In the process of analysis FTDNA have revised the timeline such that our original dates of 1500 CE are now branches down to 1850 - 1900 and 1950. See also there might be further assessments of dates and branching such that R-BY44310 is now R-BY84513. So now I am seeking the Parents and siblings (brothers) of John PYCROFT born 1792 in a place not known.

This is a PYCROFT FAMILY HAPLOGROUP simplified chart.
It is commonly indicated that the range of years for a mutation is typically about 75 to 150 years. These numbers are described in PROBABILIY CHARTS.
This family image shows mutations occuring with each generation AND / OR between siblings!
The 'Takeaway' from this observation is that there can be NO FIXED numerical of DNA time periods. Probabilities are expressions of variability.
This image attempts to show how those lineages that are different and how we all match.

This is a PYCROFT FAMILY HAPLOGROUP chart.

See here the [Relationship Box Chart] as output by BROTHERS KEEPER.
This began as two [2] Screen Shots made with [SnagIt] of 2 Displays by BROTHERS KEEPER. These were combined in SnagIt and additional shapes & texts were drawn and arranged over it.
The whole was then saved as "jpg" file. -- | -- See that I have added the Autosomal cM values for comparison.

This shows where I expect to find Autosomal and Y-700 DNA matches who might have their ancestry going back into the mid-1700s.
The family of John PYCROFT, born (about) 1792 is now a fascinating research.
If folk who are matches are found to be 5th or 6th cousins and show for us a COMMON ANCESTOR then these I will be most pleased to correspond.

A spread sheet showing how it is that I need to focus my research and DNA activity.
It will not be easy locating a match with such small cM values and have a tree with an ancestor going back into the mid 1700s.
