This Thoraldus and his son
Walter de Strivelyn
are showing both born 1125
It's more likely Walter was born 1125 since his son Peter was born abt. 1150
Unfortunately, Walter has no profile notes but Thoraldus' notes state: Thoraldus was born before 1147 – probably ca 1070-1090
which would fit for him to have been born perhaps around 1100-1105, using the generic estimate of 20 years per generational difference, but that's just guesswork since it's clear that historically it doesn't seem anyone knows when he was born other than 'before 1147'
