I happened upon this posting.Did I ever respond?I don't see that I did at least not on this forum.
The following is what I have for brothers/sisters of Cap't David Haacke. Most of it given to me by Mark Haacke. Elizabeth-(m) Dietrick Steffens (Stiffins) Mary Anne died young; Cap't David; Christina (m) J Brandel; Henry (m) 1.Ann Alexander (2) Maria Rouse; George (m) Sophia Quantz; Mary Anne (born 1813) (m) Jospeh Fisher; and my ancestor Edward (m) Harriet Porter.
Edward came to Il also and lived in both Fulton and Jo Daviess Counties before moving to Fremont County Ia around 1869.He later moved back to Fulton County Il and that is where he died.
Edwards family have changed the Haacke name to Hickey.I do believe it is in the enunciation in our area.
