Early data on 
induced reactions off protons are collected and used in a coupled-channel partial-wave analysis (PWA). Data that had been published in the form of Legendre coefficients are included in the PWA. In a primary fit using 
and 
resonances only, we observe some significant discrepancies with the data. In a systematic search for new 
and 
hyperon resonances, additional candidates are found. The significance of the known and of the additional resonances is evaluated. Seventeen resonances listed with 
or 
and one resonance listed with in the Review of Particle Physics cannot be confirmed, five new hyperons are suggested. The partial-wave amplitudes deduced in this analysis are compared to those from other analyses.
