Hi, I came across an unsourced profile (it had sources to Ancestry.com, which I can't access) which was [[De_Jesus-248]]. At first I didn't notice the problems so, taking the initial claims that Eufemia de Jesus was born around 1853 in Alva, Castro Daire and died in 5 April 1874 in Cedofeita, Porto, I've found found baptismal and death certificates backing that up, which I've linked as sources. The name of the mother is consistent, though the name of the father is unknown in the baptismal record. The death certificate also backs the claim that Eufemia was born around 1853 (29 of April, 1852, as in the baptismal record). There existence of a unnamed son and of her husband is also mentioned.
I noticed the problems when I was going to save the alterations (which I eventually did anyway), that her linked family is too young. Her half-siblings were born around half a century later and her father was only born in 1872. It's possible that it was a confusion between the name of the father listed in the death certificate (Manuel Alexandre) and the person the creator of the profile was searching for, but I would need some help on how to unravel this mess.
Finally, Ancestry.com mentions a marriage certificate with the Jose Luis d'Aguiar, also mentioned in the death one. If someone has a subscription and his able to fetch me the date and the place of the event, I would, possibly easily, be able to find the certificate and add it to the profile, in the hopes it will be able to clarify anything.
PS: Isn't the site's policy to drop the "de" from the profile Last Name? Should it be changed somehow or not?
