Is there any information on Jewish facilities for unwed mothers in the early 1890s?  A Google search brought up something the implies that the first one was established on Staten Island in 1905.

I have come across a DNA match with a NY Irish family that has an ancestor born in 1893 in New Jersey that is known to have been adopted. DNA suggests that she may have been 100% Jewish. I had been thinking that she must have been the child of a Jewish father and Irish mother because I did not think a Jewish girl would give a child to a Catholic agency.  But, perhaps the nuns were the only option in 1893?

If the ancestor born in 1893 in New Jersey was 100% Jewish, then this person would have had both a Jewish father and Jewish mother, and not an Irish mother.  

From looking online, the earliest known home for unwed Jewish mothers opened on Staten Island in 1910, so long after this ancestor was born. It is possible that this ancestor was given to the Foundling Hospital in New York City, where they took in newborn babies, regardless of ethnic background. That might explain how a baby who was partly (or 100%) Jewish ended up being adopted by an Irish family.
