TRAVERSE CITY — Heidi Ann Irving Lacey, 55, of Traverse City, passed away unexpectedly on Thursday, March 10, 2011. Heidi was born April 12, 1955, in Ann Arbor, to the late Evans J. and Roberta (Kuhnlein) Irving. She married Mark Lacey in Roskilde, Denmark, on Nov. 23, 1989. Together they raised a wonderful son, Marrek.Heidi embraced life. She loved to read, cook, camp and travel. She especially loved to welcome people to her home. Heidi's energy was boundless. She filled a room simply by walking into it, and she was quick to make sure that everyone was comfortable. It was not unusual for Heidi to be heard greeting her friends in German saying, "Hey, Schatzi!"Heidi's reach extended well beyond her family. She was a dear mother to Marrek, but many called her "Mom," knowing that Heidi would make a place for them both at her table and in her heart.Nowhere will Heidi be more missed than at Eastern Elementary. She will be missed by the students, past and present, who played with her, read with her and received her gentle guidance. Heidi's absence will also be felt by those she worked and served with at Traverse Bay Children's Advocacy Center. Children and their wellbeing were central to Heidi's life.Finally, most vivid and endearing are memories of Heidi's quirky style, contagious laughter and the complete joy Heidi found in her circle of friends. Heidi's gifts to the world were many, and they will be sorely missed, as she will be.Surviving Heidi are her husband, Mark; son, Marrek; siblings, Gary (Carol) Irving and Robert Irving; mother-in-law, Arleen Lacey; brothers and sisters-in-law, Margo (Bill) Sirrine, Marsha Chapman, Marlene Dennis, Martha Hornback and Marla (James) Doss; and several very special, nieces, nephews, cousins and friends.Heidi was preceded in death by her parents; sister, Pamela Irving; and father-in-law, Richard Lacey.Visitation for Heidi will be held today, March 13, 2011, from 5 to 8 p.m., at the Reynolds-Jonkhoff Funeral Home.
