Est. 1855 · Built by Edward Mynderse in 1855 in Italianate style · Expanded to 23-room Queen Anne mansion by Partridge family (1875) · Becker family ownership 1890–1961 · Houses Seneca Falls Historical Society collections since 1962
The site at 55 Cayuga Street in Seneca Falls has been continually occupied since Edward Mynderse built a small wooden one-room structure there around 1823. Mynderse—a prominent local figure in the Erie Canal–era commercial economy—replaced the original building with a two-story Italianate brick home circa 1855.
The Partridge family acquired the property in 1875. Mrs. Leroy Partridge undertook extensive remodeling that fundamentally changed the building's character, adding a third story and expanding the total to 23 rooms in the Queen Anne style that was fashionable in that decade. The result was a substantial mansion with varied exterior detailing and large interior spaces.
The Norman Becker family purchased the mansion in 1890. The Beckers were a prominent Seneca Falls family and the house remained in their ownership until 1961–1962, when Florence Becker—the last Becker resident—sold it to the Seneca Falls Historical Society. The organization has operated the building as a museum and archive for Seneca County history since then.

The Becker Mansion's paranormal tradition is built around two figures whose connection to the house is historically grounded. Edward Mynderse built the original 1855 structure on the site and reportedly has not accepted subsequent alterations. Staff accounts describe doors held shut from the inside and pictures turned to face the wall—specific, low-grade disturbances that the building's tradition interprets as Mynderse objecting to the renovations that transformed his Italianate home into a Queen Anne mansion after the Partridge family took over in 1875. The parlor and dining room, which are in the added sections, are where the Mynderse activity is reported most often.
Mary Merrigan was the longest-serving domestic employee of the Becker family and lived in the third-floor attic room during her years of service. Two categories of phenomena center on her: visual sightings of a woman looking out of her bedroom window, and olfactory reports—employees describing the smell of fresh bread and molasses cookies baking in the mansion's kitchen. Staff describe the kitchen as one of the most active areas for this type of sensory report. Paranormal investigators conducting formal sessions at the mansion consistently note the attic bedroom as the area producing the most documented anomalous activity.
The mansion's annual October Haunted Mansion Tours use costumed reenactors to portray these figures—Mynderse, the three Beckers, Mary Merrigan, and others—in a living-history format rather than a theatrical horror event.
Notable Entities
Annual living-history ghost tours every Tuesday in October. Staff and volunteers portray former residents of the mansion including Edward Mynderse, three Becker family members (Catherine, Norman, and Florence), and Mary Merrigan. Two sessions: 5–8pm and 9pm–midnight. Cost $50 per person; $10 discount for Historical Society members. Reservations required.
Regular guided tours of the 23-room Victorian mansion covering Seneca Falls history, the Mynderse and Becker family stories, and the building's architectural evolution from Italianate to Queen Anne. Tours start on the hour; last tour at 3pm.

Charleston, SC
Magnolia Plantation was established in 1676 by Thomas and Ann Drayton, English settlers from Barbados, and remains under the control of the Drayton family after fifteen generations. The plantation's wealth derived from Carolina Gold rice cultivated by enslaved Africans. Magnolia opened its gardens to the public in 1871, making it one of the oldest public gardens in the United States.

The Salem Tavern was built in 1784 to serve travelers stopping in the Moravian settlement at Salem, North Carolina. The Moravian congregation built and operated the tavern — a common enterprise in Moravian settlements — as a source of revenue and a place of hospitality for outsiders. President George Washington lodged here in May 1791 during his Southern Tour, an event documented in his own diary.
Newark, NY
On March 31, 1848, sisters Kate (age 11) and Margaretta 'Maggie' Fox (age 14) reported communicating with a spirit through a series of knocking sounds in their Arcadia Township farmhouse, touching off the American Spiritualist movement. The sisters later confessed the raps were produced by cracking their toe and knee joints. The cottage was moved to Lily Dale, NY in 1916 and destroyed by fire in 1955; Wayne County preserves the stone foundation as a public park.
