Hole doped high-T{sub c} oxide of TlBa{sub 2}Y{sub 1{minus}x}Ca{sub x}Cu{sub 2}O{sub y}, Tl-1212, has been investigated by {mu}{sup +} SR technique from an insulating to a superconducting (SC) region. Fast and slow precession components of the muon spin asymmetry which are due to an antiferromagnetic (AF) ordering of Cu-spins were observed from x=0 to x=0.5. The magnetic transition temperature (about 400 K) and local {mu}{sup +} fields were found to have no x-dependence. No sign of the magnetic transition was observed for x =1.0 down to 1.8 K. The correlation between the AF ordered state and the SC state at the boundary of the two states (x=0.6) was examined.
