OK this is really cool and a lot of things make sense now. I found an original homestead deed for 160 acres in my great great grandfather's name, Joseph Beckwith, dated 1873. There was also a deed for an original homestead in the name of Lucia Metcalf dated 1862. Metcalf was my great great grandmother's maiden name. Both were for a 1/4 section. Apparently they were married after Joseph came to Custer County and she was the family that escaped the New Ulm Massacre in 1862 and went straight to Nebraska and lived there 10 years before he arrived.
He also received/purchased 3 other 1/4 sections in 1873 but they were not homestead deeds as they were acquired originally in 1820. So in 1873 he owned one and a quarter sections at least. My grandmother's maiden name was Beckwith so that's the family line.
Truly amazing and my profound thanks for the resource and to
@hothouse_corn for the history lesson on the Homestead Act. A lot of pieces fell into place and it's nice to see that all the stories I heard as a kid from the old folks were true.
