You were adopted into a poor family in Ireland 65 years your biological mother is landed gentry with an estate worth 6 million do you have any rights as the only biological child from that family?

You may have rights. However, it sounds like you should invest in an attorney to determine what those rights might be. There is usually a statutory period during which an omitted heir must make a claim so you should act with no further dealy.
