Patricia Dorothy Hartmann (September 26, 1943 – February 28, 2026) was born to Norman and Patricia (Pfannkuchen) Robertson in Baltimore, MD. Her mom gave her the nickname "Sis," and Pat lived up to that name by caring for so many, including her late brother, Roland Robertson.

Pat loved Jesus and was a member of Martini Lutheran Church in South Baltimore. She believed that the Lord put us on earth for "loving, caring, and sharing," and that is exactly what she did.

Pat loved her family and phone greetings would begin with, "Hi Cousin, this is your Cousin." She was especially close with her cousins Karen and Bob Keck, Elliott Robertson, and Lance and Alyson (Shanabrook) Robertson. She loved being "Aunt Pat" to Ava Hall, the daughter of her cousin Emily Reinhardt.

Pat retired from "the gas company" after working there for over 40 years. She made lifelong friends including Barbara, Richard, Chris, and Patty.

Pat enjoyed making crafts and volunteered to teach classes in many places, including a nursing home where her elderly aunt was a resident, as well as at local churches. She loved animals and indulged her cats—leaving a small stream of water running so they could have fresh water during the day.

Psalm 13:5 But I trust in your unfailing love; my heart rejoices in your salvation.
