Margaret Baxter KRAUSE, born 7 August 1881
Frederick Robert KRAUSE, born 17 Nov 1883,
Theodore KRAUSE, born 21 June 1886,
And then - (as already posted by Yogi)
Richard Charles KRAUSE, baptised 7 September, 1893 at St Stephen's church, Richmond, resident Richmond (this record does not give either parent's name).
I would guess that, for whatever reason, Richard's birth was not registered, or recorded wrongly.
Would have been a busy day getting 4 littlies ready to go to church.
