Vanarama Conference South club Farnborough have added Aaron Tumwa and Curtis Shaw to their squad.
Tumwa joined Blackburn Rovers on a one-year contract a year ago.
The 19-year-old joined on a free transfer following his release by Watford.
He spent most of that summer on trial with Rovers, playing with their under-21 side, featuring at left-back and centre-half.
Tumwa, who had a loan spell at then Ryman League Premier Division side Wealdstone when at Watford, spent most of last season in the Rovers development side before being released at the end of last season.
Much-travelled Shaw, 27, ended last season in the Southern League Premier Division with Arlesey Town.
The Nottingham-born midfielder previously had spells with the likes of Kidderminster Harriers, Shepshed Dynamo, Hucknall Town, Matlock Town, Ilkeston Town, Mansfield Town, Bromley, St Albans City and Bedford Town.
