Welcome to the Genealogy Lady website! I have been doing genealogical research for over twenty years, and for clients since 2001. Genealogy and history are my passion, and I hope my enthusiasm is contagious.

I research families throughout the United States. However, my own family hails from New England and the Midwest, so I am more experienced with the resources available in those geographic areas.  In addition, I have ancestors who arrived on the Mayflower as well as many who served in the Revolutionary and Civil Wars. Quaker and Schwenkfelder (Pennsylvania German Protestant) research are two additional areas of my expertise. I am a proponent of DNA and genetic genealogy, and I look forward to all the exciting ways this tool will be used in the coming years. As a resident of Northern California, I have access to local repositories and records only available here.

I adhere to the Genealogical Proof Standard and the Association of Professional Genealogists code of ethics.

Please consider hiring me for your genealogy and family history needs. Contact me for a free consultation.

You can find me on the following social media websites:





What People Are Saying About Deborah…

“Deborah is a remarkable genealogist! With only minimal information provided by me, Deborah found many relatives and whole family lines that I didn’t even know I had. She works with passion and precision and gets my highest recommendation.” – Andrea from New York

“I wanted to know more about my mom and dad’s parents and siblings after the death of my father two years ago. Deborah shared information about her own family and how she acquired knowledge and skills to research her family history. Speaking to Deborah daily about genealogy sparked my interest even more to do research on my family. Deborah provided me with tips about census research and came up with information about my family members that kept me interested in finding out more. Because of Deborah, I’m preparing to do DNA testing to really get the ball rolling.” – Marianna from Northern California

“Genealogy is not for the faint of heart, because it is actually a subdivision of history, one that requires meticulous attention to detail and extraordinary tenaciousness. In the work I’ve seen Deborah Sweeney do, I have been so impressed by her persistence, sometimes pursuing research to dispel family tree mysteries for a couple of decades. Her motto seems to be, “If there is a document to be found, I will find it” and she has the strong instincts of a historian to know which stones needs to be turned. DNA expertise is also one if her research tools. She is an awesome genealogical scholar.” – David M. from New York

“Deb has pointed us in the right direction on numerous occasions knowing that we are the hands on type.  She knows how to dish out the clues so the surprise is real and true when we find the gem.” – Dan & Sue from New Hampshire
