Added a new Surname Variants search option to the Cross-Reference Search, which now includes variants of the selected surnames in the search. 
In the previous version a search for Sullivan and Collins would only have located any parish where exact matches to both the surnames appeared, the ‘Include Surname Variations’ option would also utilize similar surnames in the search such as OSullivan, Sullivans, Sullivane etc, and Collin, along with misspellings and possible typos such as Colliins, Sullivn etc.
The surnames variants used in the search can be displayed by ‘hovering’ the mouse pointer over each of the surnames in the column header.
