First, I would like to introduce Peter ... Those 3 dots are not an ellipsis - they are Peter's LNAB!!! If Peter had parents or siblings, we don't know anything about them. Neither do we know the dates or places of Peter's birth, marriage, or death, but he and his wife had four children - Castor, Emma, Mathilda, and Peter. None of the children have any dates or places associated with their lives, nor do we know anything about whether they married and/or carried on the ... family line.
I find the "..." a rather novel variant of what should be "Unknown", but it may surprise you to know that there are 194 WikiTree profiles with that surname. Three of them even have the same first name!
OK - enough tongue-in-cheek commentary - what should we do about all the members of the 3-dot family line? Peter and his children were entered in 2011 by a profile manager whose last contribution was the same year. There are several profile managers of the 3-dot profiles and most of these profiles have red or green privacy and were entered between 2009 and 2013 and not touched since they were created.
