I had not heard of
https://www.gedmatch.com/ before and I cannot find any details of the
GEDCOM dialect it prefers.
But since it appears to be a free service I might find time to experiment with different
GEDCOM dialects.
how_to:exporting_gedcom_with_multimedia|> Exporting a Family Tree with/without Media explains the process, and I will highlight the options for your objectives below.
In the how_to:exporting_gedcom_with_multimedia#export_gedcom_file_command|> Export GEDCOM File Command section you will select your father on the left and click
> Add to Selection button. Then click
Add using Query button and choose
Ancestors. Leave the
Exclude records options at default settings. For the
Media Records option select
Exclude to eliminate all the
Media records & files, because none of your target websites can upload media.
In the how_to:exporting_gedcom_with_multimedia#export_to_website_without_sensitive_data|> Export to Website Without Sensitive Data introduction consider whether
[[private
]] text or the
Living flag need to be added before you even use the how_to:exporting_gedcom_with_multimedia#export_gedcom_file_command1|> Export > GEDCOM File Command.
Skip the how_to:exporting_gedcom_with_multimedia#clean_unwanted_fields_plugin|> Clean Unwanted Fields Plugin section.
Use the how_to:exporting_gedcom_with_multimedia#clean_living_persons_plugin|> Clean Living Persons Plugin to privatise your father.
Skip the how_to:exporting_gedcom_with_multimedia#file_split_tree_helper_command|> File > Split Tree Helper Command section.
Repeat the how_to:exporting_gedcom_with_multimedia#export_gedcom_file_plugin|> Export Gedcom File Plugin section three times for
FamilyTreeDNA and
Ancestry and
GEDmatch. The first two have specific export modes predefined for those websites. For
GEDmatch try
(Std) Standard GEDCOM 5.5 until we know better. You will not need to set any
Extra Options.
Checkout the Plugin
Help & Advice pages for
Output Formats for each chosen website where there are also
Import Details for the website. All that advice is also in plugins:help:export_gedcom_file:export_gedcom_file|> Export Gedcom File Plugin that you can peruse beforehand.
BTW: You can use a free
Ancestry account if you are only interested in uploading a tree and not extracting records.
