Hi to all you Walshes, I'm throwing in a little bit in case it's of any use to you, a little too far distant from my own tree really.
A stone in The Grange Cemetery, Wexford reads
"Erected by Alice Walsh in memory of her father William Lambert who died July
1st 1861 aged 50 years also he mother Alice Lambert who died Oct 6th 1881
aged 70 years."
Alice Lambert is my great grandmother whose maiden name was Furlong. Amongst William and Alice's children was Alice, the youngest, born and christened 12th Oct 1848, godparents Godparents - Nicholas Hayes and Mary Petit.
She obviously married "somebody" Walsh but his name is not known, however, family stories say that their son went to be a sheep farmer in the Falkland Islands.
This is my total knowledge of the Walshes but since the name Furlong has been mentioned in this thread I thought this little bit might help.
