Piedad's birth last name is RAGLAN; the daughter of Samuel Raglan; not Adolph Buttner.
There is no research that I have located that indicates that Piedad and her brothers Harvey and Morris were legally adopted by Adolph Buttner and Dolores Serna.
Their mother was Magdalena Serna, the sister of Dolores Serna who was married to Adolph Buttner.
Magdalena found herself with 3 young children as a single mother, Samuel having removed himself from the family picture. So I guess you'd say, the three children became wards of Adolph & Dolores.
And, when that occurred, it seems that the children assumed the name BUTTNER. Their descendants have remained Buttners for well over 100 years.

The following information is from correspondence Immaculate Conception Church regarding their marriage.
They were married at Immaculate Concepcion Church located in Yuma, Arizona.
Their names were recorded as: Augustin George BUTINER
Dolores CERNA
Their parents were recorded as: Agustin BUTINER & Bertran BUTINER
Jose Maria CERNA and Rafaela AMAVISCA
The letter was signed by Priscilla Arviso, Secretary
NOTED: The spelling of both Agustin & Dolores' last names do not agree with other primary documents. Since Adolph (Agustin) consistently used the last name BUTTNER, I believe this is the correct spelling.
Re: CERNA. Probably a mistake on the part of the person registering their marriage as CERNA would not be spelled with a "C", but rather an "S" in Spanish. Again, human error.
What is interesting is that it seems neither Adolph or Dolores corrected their marriage document. A marriage certificate is considered a primary document used throughout one's life to verify an important legal date, one's marriage date.
It could be that in 1874 in Arizona Territory it was not deemed as important a document as in 2024.
