Policy:
My policy has been to include blood relations and their spouses. I haven't attempted to build out family trees of spouses. If anyone wants to add relatives of their spouses, they are welcome to do so.

Tree View:
The tree doesn't show all people at one time. To see more people connected to a person, press the 'Tree' button on that person to expand the tree centred on that person

Magrill: 
The transliteration of the name in Cyrillic is Magaril, and this form appears in many of the records. The Russian 'g' character was frequently used in place of an 'h' sound which does not exist in Russian. Note that some of the Magrill family in Israel continued to use the form Maharil in parallel. 
Here I have consistently used the English form Magrill.
There is a branch in the US that continues to use the form Magaril but I have not yet established a relationship to our branch.

Levi:
On the Levi side name family was originally Benjamin and changed to Levi on immigration to UK (!). Various members used Levi / Levy / Lever
