LindaR,
Are you aware that your ancestor Richard Henry Mooney is listed in Charles Nutt's, History of Worcester and its People,Volume IV, Page 514 - 517?
The first paragraph reads as follows:
"The Mooney family represents in the present generation in Worcester by Richard Henry Mooney, A.M., and John Francis Henry Mooney was founded in this country by Richard Mooney, farmer , who come from Carrick-Beg, County of Waterford, Ireland in 1840, and settled in Worcester, Massachusetts. He was accompanied by his daughter and son-in-law, Mr. and Mrs. John Blade, and his two sons, Richard and Nicholas, his wife, Nancy (Hagerty) Mooney, having died in Ireland. Richard Mooney, accompanied by Mr. and Mrs. John Blade, went to Wisconsin, where he engaged in farming, and subsequently became the owner of the largest and most productive farms in the region, which he cultivated and improved, and upon which he resided to the time of his death at the age of eighty-eight years. Nicholas Mooney, mentioned above died in Worcester, June 12 1848, being the first person buried in St. John's Cemetery."
It appears that your ancestors were quite distinguished. Mr. Nutt gave them 3-1/2 pages.
It looks like Worcmik's notes might be right about the first burial at St. John's.
Do you have access to the Worcester Public Library (WPL)? If not, maybe I can make arrangements to get you a copy of the above mentioned pages.
