My Irish Dad died

[Brooke]

My 95 year old Dad, who was born in Ireland, died recently, and we are having a memorial picnic in a grove of redwood trees (which he loved). Dad was not particularly religious, so that eliminates lots of memorials, but he loved life and nature. Is there a reading that has Irish roots other than the "road rise to meet you" one? Or perhaps something celebrating nature? Thank you.
