Randal, I hope you have had some luck.Johann and Heinrich are ubiquitous within the Mackes. I am not assuming that the following Heinrich Macke is your ancestor but the book might be helpful. I do not have a copy but a good library, should have access to it.Especially in a Nebraska with its many ethnic-german families.
Name: Heinrich Macke Year: 1833 Place: America Source Publication Code: 8595 Primary Immigrant: Macke, Heinrich Source Bibliography: SMITH, CLIFFORD NEAL. Emigrants from the Former Amt Damme, Oldenburg (Now Niedersachsen), Germany, Mainly to the United States, 1830-1849. (German-American Genealogical Research Monograph, 12.)

Please let me know what you discover.My ancestor was also a Johann Heinrich "Henry" Macke from Amt Damme, Grand Duchy of Oldenburg.
