We report the variation of ferromagnetic order in the pseudo-ternary compounds URh1-xCoxGe (0 <= x <= 1). Magnetization and transport data taken on polycrystalline samples show that the Curie temperature T-c gradually increases with increasing Co content from a value of 9.5 K for URhGe to a maximum value of 20 K for x = 0.6 and then steadily decreases to 3 K for UCoGe. The magnetic interaction strength varies smoothly across the series. For all samples the electrical resistivity for T < T-c follows the behaviour rho = rho(0) + AT(2). The A coefficient is dominated by scattering at spin waves and is strongly enhanced for x = 0 and 1.
