Hello Paul and the rest of the Abreu community. Hope this message finds you and maybe some other relatives.
Eulalia Abreu was my grandmother. Her maiden name was Echeverria and was married to my grandfather in Cuba known as Cuña.
She had only one son, my Father Jose Antonio Abreu who emigrated to Costa Rica in the late 50's where my grandfather died. My Grandmother Eulalia migrated to the USA after my grandfathers passing where she lived with her sister Laura. They both passed away in Miami about 10 years ago.
My father was married twice. had two sons and one daughter from his first marriage who still live in the USA and I am the only son from his second marriage. I live in Costa Rica where there is another branch from the Abreu family. The son from my grandfathers brother Pedro Abreu but even in such a small country and with friends in common I have yet to meet anybody from that branch of the family so I know little about them.
Hope this helps a little and thru this I can reach out and meet more family members.
