This user is especially interested in breaking through intercontinental immigrant "brick walls".

Intercontinental immigrant brick walls
Tables in this section show data from FamilySearch. Indexed historical records divided by Family Tree profiles gives a very rough estimate of the completeness of a surname study. The estimate is not intuitive. A large ratio usually means many profiles have yet to be created. However, a small ratio does not mean the study is complete. There are surnames for which many profiles exist but almost no historical records have been indexed by FamilySearch; in this case the ratio is less than 1. It has been my experience with some rare surnames that when all historical records are linked to profiles, there are about 7 records per profile. That is, the sweet spot is 7.

Clough in British Colonial America
A young single man named John Clough was among the early 17th century immigrants from England who settled on Martha's Vineyard. His place and family of origin in England are not known. The surname Clough is not rare, and there are many known spelling variants. Numerous villages in Ireland and England are named Clough and in northern England the word clough means a steep sided valley.

This table reveals that FamilySearch Family Tree contains over 40,000 profiles with neither standardized place names nor historical records attached. Note, however, that the worldwide number of records divided by profiles is near the "sweet spot". This suggests that nearly all profiles relating to this surname already exist in Family Tree, but most profiles have not been reworked since the mass import circa 2012 of legacy trees into Family Tree. This situation begs for a community project. Many hands make light work.

Verry and Yarrall in New Zealand
Verry and Yarrall families were among the first immigrants to New Zealand; there is good documentation of these families in New Zealand but their origins in England are unknown. Numerous genealogists have worked on tracing back the Verry line, so far without success.
