I have seen that we all have an Esquer from Sonora. Mine is my husbands great grandmother Maria del Rosario Esquer born around 1878 we think in La Dura, Sonora. We know she married Juan Garcia and they lived in La Estancia, Sonora (according to the 1930 census)were they had about 11 children Manuel Garcia Esquer is the oldest and my husbands grandfather, then follows Guillermo, Adelina, Aurora, Rosario, Miguel and I am not sure of the others. If anyone has anymore info I would really apreciate it.
