The trick seems to be in putting in only a bare minimum.

Starting at the home page, click on "search records" tab next to "home" tab.

New screen appears. Click on Int Gen Index on left hand khaki strip.

New screen appears with IGI highlighted. Go to "Father" and put in first and second names. For "mother" put in first name. Go down to "Year" and put one that's midway between earliest and latest you expect to find. Then add a year range to suit. Next "Region". Put in British Isles, and screen changes to give you the choice of IOM, England etc. Then click Search.

Hey Presto.

Go down the list and identify the ones which you know are correct.

This is a good method for discovering the maiden name of a mother who you only have a first name for.

I too floundered for 3 years on Familysearch until I read a similar posting a few months ago.
