Typically, The Morrigan 
is 1 or 3, I suppose she could be 2 if She wanted. 
I work with Her regularly & have for about 2 years.
So, I would look into possibly “Odin” or maybe “the Morrigan”, but also definitely follow your intuition.
I only mentioned Odin originally because, while I don’t work with Him, my oldest son does & has for quite some time. I asked him about the 2 & that’s when he said that when there’s 2 crows around when he is out, he knows Odin is around for 1 reason or another.
In my experience with the Morrigan it won’t be a 1 time occurrence if She is trying to reach you for something & it will become almost persistent & multiple times throughout the day & not just with crows
A good place to start your research on either is with their Pagan Portals books. I’ll have to ask my son about other good places for information on Odin.
Along with the Pagan Portals series by Morgan Daimler, there are books by Stephanie Woodfield (Priestess of the Morrigan), Morpheus Ravena (dedicant of the Morrigan), Courtney Weber, & I can’t remember the other author’s name off-hand… that are good sources of information about Her & working with Her. I would start with Pagan Portals for kind of initial information on the Morrigan & go from there. There are 2 & the first I believe is called The Morrigan: Meeting the Great Queens & then the 2nd in the series is Raven Goddess: Going Deeper with the Morrigan.
As for Odin… I’d also start with Pagan Portals & I can get back to you on other sources once I can talk to my son later today.
