Baby Name Help! (For a story)

So, in my story, the main character is a woman named [name_f]Hazel[/name_f] [name_m]Felix[/name_m] living with her husband, [name_m]Oscar[/name_m], and two little sons. The sons are the problem. Both [name_f]Hazel[/name_f] and [name_m]Oscar[/name_m] really love nicknames, and I would love for the two little boys to be [name_m]Tobias[/name_m] ([name_u]Toby[/name_u]) and [name_m]Julian[/name_m] ([name_u]Jules[/name_u]) but [name_m]Tobias[/name_m] [name_m]Felix[/name_m] and the repeating “s” sound just doesn’t strike a chord with me. [name_f]Hazel[/name_f] also has a brother who passed away just after the younger son was born, and I’d like to incorporate his name ([name_u]Owen[/name_u]) into the mix. Thanks for your help!

[name_m]How[/name_m] about using a T first name with a middle name of [name_m]Obadiah[/name_m], [name_u]Oberon[/name_u], or [name_m]Obrien[/name_m]? That way his name could be something like [name_m]Thomas[/name_m] [name_m]Obadiah[/name_m] and be called [name_u]Toby[/name_u].
