How do I remove an entire ancestry line found to be in error?

Question

I spent years researching and developing the Luke Nelligan, County Kerry line of my grandmother Catherine Antoinette (Nelligan) DeLeonardis.  Finally when I found the will of her "mother" Catherine Nelligan, it clearly stated in several places "raised as my child since age three".  I have been unable to find (yet) the true lineage for her French father, as shown in the 1920 census.  How do I disconnect my grandmother from the Nelligan line?

Answer 1

In a case like this you may want to use the option to mark her father and mother as non-biological, rather than disconnecting them outright.

There is so much we inherit in our cultural and personal habitus from those who raise us, whether they are biological parents or not.

Answer 2

Do you want to disconnect the parents altogether? Just select "edit mother" which then gives you the option to "remove as mother"

However

If you have a look at the edit page for your grandmother you will see where it says "edit mother" there is an option to select "mother is non-biological" which will keep the family relationship together. You can then offer an explanation in the bio section.

Answer 3

Unklike the other two, I prefer to see the biological parents (insofar as they're known as father and mother and put the adopted or raised relationships in the Biography.  The other way may confuse things for people trying to do DNA genealogy and in figuring out connections with other lines.  If, after all, you don't know who the biological mother was, you don't know it and you might as well make it clear so another genealogist who finds a strange daughter (or mother) in a line he thought might relate to him figures this isn't the right ling after a too quick glance and you miss getting the right connection. But do use both the mother who raised you ancestor and an unknown mother when searching elsewhere since you don't know  what name may be in an obscure source.
