The presence of a comma in the data entered will determine which way the data will be interpreted. In both circumstances, no significance is placed upon the case in which the names are entered.
Partial names are possible.
If only one word is entered, Relatively Yours will treat it as a surname or part surname. If only a partial name that includes a given name is provided, then the surname must be in full. Names, even in combinations of surname and four given names, are not necessarily unique. This is particularly so in genealogy whereby given names are quite often passed from family member to family member. The facility is available to the user to select the correct person from the possible candidates displayed.
