Browne's of Batt Street, Wexford

Looking for relatives of my Mother Annie Browne (b 14/6/1921) - one of twins, lived in Batt Street in Wexford for many years. Siblings included brother Lawrence (Larry), Josephine and Greta. Father was Thomas Browne and Mother was Mary (I think). Any info would be gratefully received. Annie (known as Anna) left to UK and married a John O'Brien from Bootle, Lancs. Had 5 children including me. Now a grandmother and would like to visit Wexford but prefer some information prior to coming if possible. I know one of my cousins married a Lett who owned trawlers there. (Ann & Lance (Lawrence?) Lett) - they lived in Enniscorthy I think (I visited in 1982)
