Surname Index and Relationship Project
(SIRP) is a "structured extraction and research system used to identify
individuals and combine them into family units". In 2011, SIRP was
successfully used by the Brough Family Organization to identify and connect
hundreds of individuals living in two countries.
SIRP acquires online genealogical data from
multiple sources on individuals having the same (or similar) surname in
a designated geographical area, then inputs all such names and their associated
dates and places of births, christenings, marriages, deaths and burials
into a PAF-style (and GEDCOM friendly) database. Once this database has
been compiled, then analysis, screening and merging tools are used to
match and link individuals together into related families and larger ancestral
Some of the genealogical sources used by
SIRP include the following:
1) LDS Ancestral File - still available
at some Family History Libraries and/or on earlier (DOS-style) computer
2) Pedigree Research File (PRF) - still
available at Family History Libraries.

In 2011, the Brough
Family Organization used SIRP methodologies to compile databases of
hundreds of "Brough" surnamed individuals who had lived from
1800 to the early 1900's in New Zealand and in New South Wales, Australia.
Subsequent analysis, screening and merging of these databases resulted
in the rapid identification of numerous linked individuals and multiple
At the present time, the BFO is applying
SIRP methodologies to identify and combine thousands of individuals and
their families who lived in the 1800's and early 1900's in England and
