well that is very interesting. The father Edward Dougherty died in 1889 so the mother Marcella may have been having a difficult time.
Was there a Mary Ellen Dougherty in those registers. Sorry if you do not have easy access to them.
Are they searchable online. I am looking in the State records archive search but can not even come up with Marcella Dougherty.
This is becoming more and more a puzzle that seems like it may have been rather sad.
