I'm looking for anyone by the name of Brennan, Helms, and Gerdes in Nebraska who is related to "Junior" Helms who lived in Plattsmouth, Lottie Lucille and James Brennan (Auburn and Plattsmouth), Phyllis (Brennan) Cook of Plattsmouth, Gary and Dean Brennan in Lincoln, and Barbara (Brennan) Schultz of Plattsmouth; who recently passed away.
My request has to do with writing a family tree book on Brennan / Helms. Any information you can provide me would be greatly appreciated. Thank you.

David Cook - son of Robert and Phyllis (Brennan) Cook of Plattsmouth
