I've spent a while merging many people in several long family lines,
and came up with a step by step process described here, before I add
it to
http://www.wikitree.com/wiki/Merging_multiple_profiles. Sorry
for the long message, I'm very process-oriented. Comments and feedback
welcome.
I've found between 5 and 20 duplicates for many of my ancestors before
1700. Most of this process doesn't require supervisor access, though
you have to wait for the other profile owners to approve access and
perform the merges. Starting with the oldest ancestor works around the
problem of merging different parents when merging children.
For a family line with many duplicates:
1. Start with the oldest ancestor shown as a duplicate in
http://www.wikitree.com/wiki/Special:FindMatches (your own ancestor
potential matches). I usually search across wikitree, +- 2 years,
require dates, don't allow for century typos, and don't show proposed
or rejected matches. I wish I could set those as defaults to use every
time.
2. Start with the oldest duplicate ancestor in the list first. Show
the ancestor lists for all duplicates, to find the oldest duplicate
person. That person may not be on your watchlist so they won't show up
as a match in the original search. Start with that person / family
group, husband first. First / last names may have different spellings
for the same people.
3. Run WikiTree search with the same name(s) to find ALL duplicates,
because they don't always show up in #2. Since the search is NOT a
soundex or fuzzy match, you may have to search several times with all
name variations. Since firstname/lastname results are NOT sorted by
date and there is no date filtering available, you have to work your
way through all possible duplicates in the entire result list, which
may be very long for common names like Henry Adams or John Wright.
4. Line up all duplicates for a person next to each other (I use tab
windows in the browser) in order of creation (oldest first). Typically
it's by number order after last name, unless there are variations on
the lastname spelling.
5. You may find people with the same name but missing dates. Open
those people too, to see if they are the same person (based on family
relationships). If they are, fill in at least the birth date. It's
amazing the number of people that add profiles without even an
estimated before/after date.
6. Once you have all possible candidates, verify that they really are
the same person, based on birth/marriage/death dates and locations,
parent/spouse/child names and relationships. Close the ones that are
not the same person, making notes of any data issues such as improper
relationships (parents too young, multiple children in the same year,
duplicate children).
7. If you have permission or the profile is 300+ years old or open,
fix any incorrect or conflicting data (dates, locations) in the
duplicate profiles. Don't worry about missing information. If you see
incorrect relationships, don't merge that profile until the
relationships are fixed. If there are multiple variations on the first
or last names, add those variations to the alternate names. Add
missing last names or missing maiden names, if allowed.
8. For each duplicate, request to join the trusted list, This notifies
the profile owners that you are a related descendant, and makes your
access permanent instead of temporary. I paste a stock request such as
'Merging duplicate profiles and adding ancestors/spouse/children. I am
a descendant.' and may add specific information about how I am
descended (through XX child or grandchild) if a historically
significant ancestor or family line. Take control of any orphaned
profiles.
9. From all the candidates, decide which profile will be the surviving
merged profile. For each duplicate profile pair, create a merge
request at
http://www.wikitree.com/wiki/Special:MergePerson with the
IDs merging every later profile into the single earliest profile. This
also notifies the profile owners of the specific merge request, and
adds it to the profile history as a pending merge.
10. If you are a supervisor and want to manage the merged profile, you
can add yourself as a profile manager to the single earliest profile,
at the same time merging your own personal ancestry information into
that profile. You can also remove the other profile managers, though I
have not done that on any duplicate profiles. Or you can simply add
yourself as profile manager to both profiles and do the merge
yourself. I do think it is important to at least ask permission and
notify the other profile owners though.
11. I find many owners very responsive and helpful, and they do the
proposed merges sometimes very quickly. Others may take a long time to
respond.
12. When all duplicates for a single person are merged, we can clean
up the description and source info as suggested by Lianne. The merge
process simply adds all text notes, so people can't complain about
losing any information, until we start to clean up the description. I
may clean up some of the text in step #7 if the information is truly
not useful ('imported from gedcom, ancestry', etc).
13. As an additional validation, I periodically export the gedcom and
import it into a program such as RootsWeb or FamilyTreeSearch, and run
the data validations. This is extremely valuable for finding improper
relationships and improbable/impossible dates.
Though the description at
http://www.wikitree.com/wiki/Merging_multiple_profiles
is good, it doesn't detail the entire process of merging entire family
trees. Though this is a tedious process, in the end the data and
relationships are much more complete.
