I adopt a classification scheme for the different Roper families as
determined by the Y-chromosome tests. In order of time at which the Y markers
were determined, the classification is:
| Family Class |
Abbreviation |
Participants |
Comments |
| RoperY1 (branches
RY1V, RY1M, RY1E) |
RY1 |
Many USA Ropers,
PJR(RY1E), AGGR(RY1E), APR(RY1E)
RY1M=RY1 Massachusetts
RY1E=RY1
Suffolk/Norfolk, England |
Previous notation: MUR for those members in the USA
RY1E=English branch
EMUR=MUR+RY1E=England/USA Roper family |
| RoperY2 |
RY2 |
LWR(RY2a),
GWR(RY2b) |
An English Roper
in Australia & a Diss, Norfolk, England Roper.
They differ by 4 relative
mutations; 3 of the 4 are for highly variable locations. |
| RoperY3 |
RY3 |
[CMR, RJR2](RY3a),
DSR(RY3b) |
A southern USA
Roper and a Kent Co. England Roper |
| RoperY4 |
RY4 |
DTCR(RY4a),
GAR(RY4b), WGRD(RY4c) |
Perhaps RY4 and
RY8 are the same family. |
| RoperY5 |
RY5 |
HSR, AWR, ITR,
CR2, DJR, EJR2 |
HSR & AWR are WV
USA, the rest are English (Norfolk/Suffolk).
There are no surnames which
have 1 or 2 relative mutations for 25 markers with this Roper family, so I
conclude that this occurence of the Roper surname is relatively old. |
| RoperY6 |
RY6 |
JRR, RCR2 |
A southern USA
Roper |
| RoperY7 |
RY7 |
LJR3(RY7a),
MWR(RY7b),
JHR2 (RY7c) |
LJR3 & MWR
differ by 4 relative mutations for 25 markers; only 1 of the 4 is for a highly
variable location.
MWR is Cumbria English.
LJR3 is a PA/VA Roper family
from Cumbria England.
JHR2 descends from colonial Charleston SC from
Warwick, England |
| RoperY8 |
RY8 |
CER & RER |
Lincoln, England
origin
Perhaps RY4 and RY8 are the same family. |
| RoperY9 |
RY9 |
WSR, KNR, EJR |
Descends from
Isolda Roper (bc1410 Derby England) |
| RaperY1 |
RaY1 |
DMRa, TARa &
DWRa |
There are no
surnames which have 1 or 2 relative mutations for 25 markers with this Raper
family, so I conclude that this occurence of the Raper surname is relatively
old. |
Only families with at least 25 markers and only families with two or more testees
are classified.
