On the 1870 US Census, under Frank Metriges (Metzger-264) and Apolonia Gutierrez-336, there are three young woman named Maria Metriges (Metzger-271), Pastora Metriges (Metzger-272), and Josefa Metriges (Metzger-263). Their profiles show them as the daughters of Frank and Apolonia and the sister of Maria Juana (Metzger) Korte (Metzger-270), Frank and Apolonia's oldest daughter. I think these three girls are not biologically related for the following reasons:
1) On the 1860 US Census, Apolonia has an Indian servant that shares her last name, Sofia Gutierrez. I've never seen any family tree on Ancestry or FamilySearch that includes her as a daughter.
2) On the 1870 US Census, Apolonia and Frank are both listed as white but two of the three girls are listed as Indian.
3) In 1895, the New Mexico Supreme Court issued a ruling on de Cordova vs. Korte. The three daughters of Viviana Martinez were suing Henry Korte, Frank Metzger's business partner, for half of the business as Frank's heirs. They claimed that they were his only natural daughters. Korte's lawyers claimed that Henry Korte's wife, Maria Juana Metzger was not only Frank's natural daughter but that he adopted her as well. (Apparently Frank didn't believe in marriage.) There is no mention of three other daughters with Apolonia.
Part of me says I should just exclude them until I find more information but part of me says I shouldn't be so hasty and I should look for more information first. The main reason I was happy to find this site is because I know I need a lot more training and I hoped I could get it from all the experienced people here. What would you do?
Edit to Add: It looks like Josefa Metzger might be related.
