Be sure to check out my blog for compelling stories from my own research that illustrate the exciting ways a professional genealogist can surprise, inform and bring deeper meaning to your and your loved ones’ lives by “introducing” you to the relatives you’ve always had questions about–and some you didn’t even know you had!
I look forward to helping you discover YOUR unique story!
I just wanted to say how much I enjoy your writing about the questions and problems you pursue – each blog is a terrific class in research and inquiry, including what questions to ask.

I am a native of historic Sackets Harbor in Jefferson County, New York. I was bitten by the genealogy bug there at age 10 when my mother showed me a pile of old family papers describing the origins of my middle name, Avery. Genealogy has been my constant passion ever since.
In 1996, I moved to Washington, D.C., where I performed genealogical research for clients at the National Archives, Library of Congress and National Society Daughters of the American Revolution Library.
While in D.C., I also worked as a professional indexer on the staff of the National Geographic Society, indexing more than 30 trade books and writing monthly and annual cumulative indexes to their magazines. It was there that I developed a love of indexing and publishing.
In 2002, I earned a Master of Library Science degree with a concentration in Archives from the University of Maryland at College Park.
In 2003, I moved to the Boston area, where I now perform research for hire in New England and New York State. Here I also spent twelve years leading the team responsible for designing how millions of people search and see the world’s published books and journals online for EBSCO Information Services, the largest provider of scholarly research databases worldwide.
In 2013, my genealogical and historical research was used by the New York State Office of Parks, Recreation & Historic Preservation to create the permanent exhibits at the historic Rock Island Lighthouse State Park in Fisher’s Landing, New York, earning a New York State Historic Preservation Award and a citation from the New York State Assembly.
In the fall of 2016, I earned a Certificate in Genealogical Research from Boston University, a program focused on modern methods, standards and ethics for genealogical research.
In 2018, I was honored with election as Vice President of the New England Chapter of the Association of Professional Genealogists.
My work has been published in Thousand Islands Life magazine, The Beacon, and featured in Lighthouse Digest, The Informer: The Journal of the Jefferson County, New York, Genealogical Society and the Watertown Daily Times. I am the author and publisher of several original indexes for New York researchers.
I am the creator of the Jefferson County, New York, Pioneer Portraits Project, the Rock Island Lighthouse Historical & Memorial Association, and the Hounsfield History project.
I am a current member of the Association of Professional Genealogists, the New England Historic Genealogical Society, the New York Genealogical & Biographical Society, the Jefferson County, New York, historical and genealogical societies and the American Society for Indexing.
