Prayers were said for the family during a service at All Saints Catholic Church on Wednesday morning.
The honorary consul of Poland in Northern Ireland, Jerome Mullen, said he had never experienced such a tragedy in his 18 years in the job.
PSNI Supt William Calderwood said emergency services were met with a “shocking scene”.
Police have said the cause of the deaths has not been formally established and they are not seeking anyone else in relation to the deaths.
At a press conference on Tuesday afternoon, Calderwood said they were keeping an open mind, but they were working on a “strong hypothesis” of a “double murder followed by a sudden death”.
He expressed his deepest sympathies to family members, friends and loved ones for their “unimaginable loss”.
