5 thoughts on “Find Duplicate Individuals”

  1. I’m in the process of tidying up my FTM file so that I can use FH later this year (I’ve just about exhausted what’s on Ancestry so my membership will expire later this year and I’m now subscribed to FindMyPast). I exported a Gedcom from FTM to check for duplicate individuals using FH and this plugin. If the Gedcom is simply imported as a new project then the plug-in fails to find any duplicates. Making a simple change to one individual then allows the plug-in to work although only one individual is checked.

    If the Gedcom is merged with an existing dummy project (just one individual) then the plug-in runs and finds the duplicates in the original file.

    Doing some debugging I located the issue that the plug-in requires a CHAN entry for each individual otherwise it won’t list it as a possible entry to be matched as only changed records are checked.

    I modified the code so that it would ignore the lack of CHAN and the plug-in successfully ran and found duplicates.

    This is not a major issue for me as I have a successful work around but it may be worth considering for a future upgrade of either the plug-in or FH6.

  2. Plugin error

    … Historian/Plugins\Find Dublicate Individuals.ft_lua:714: Cannot make folder: no such file or directory. No changes have been made to data records.

    • Sorry! That error message usually lists the folder path that it cannot make and would help me diagnose the problem.
      My suspicion is that the folder path includes a non-ANSI extended Unicode accented character or symbol.
      That is a potential problem for any plugin that uses folders & files and I am gradually working through my plugins to update them.
