A further six people have admitted to being involved in sham marriages in Accrington.
Nigerian Saheed Bello was this week jailed for 21 months after paying his Czech ‘bride’ Martina Demeterova £2,000 to take part in a wedding at St Andrew’s Church in the town.
She was also jailed for 15 months after pleading guilty to aiding unlawful immigration.
Her mother Kveta Demeterova, who acted as a witness at the service, was given a suspended sentence.
The convictions means that nine people have now been locked up for a total of almost 13 years in connection with sham marriages at two churches, St Peter's and St Andrews.
It is thought that more cases are yet to go before the court. All those involved have been from either Nigerian or Czech backgrounds.
Other recent cases before Burnley Crown Court include a brother and sister from who have been told they could be imprisoned after admitting assisting unlawful immigration.
And in a separate case a 42-year-old woman who was already married has been told that she could also face jail after admitting bigamy and perjury.
Hyndburn MP Graham Jones has praised the police’s efforts in bringing those involved to justice.
Mr Jones said: "The police have done an excellent job exposing sham marriages.
"There are always people who feel it necessary to abuse the system. It’s reassuring that they are now rightly behind bars sending a clear message to others."
In November last year vicars were told not to handle weddings involving Africans and Eastern Europeans after a clergy leader revealed that 40 bogus marriages were being investigated in Accrington.
The Archdeacon of Blackburn, The Venerable John Hawley, said the incidents centered around two churches in the town, St Peter’s Church and St Andrew’s.
In a bid to stop future problems, the Archdeacon called on church leaders to be vigilant and issued clergy in Accrington with a checklist to deal with any potentially suspicious marriages.
Anything deemed suspicious is then passed to the Blackburn Diocesan lawyer.
A spokesman for the Blackburn Diocese said the Church of England is doing all it can to stop sham marriages taking place.
He said: "It is distressing when a small minority of people abuse the church’s hospitality and trust to betray Christian marriage in the way these court cases have disclosed.
"The church is continuing to monitor these cases and will work with the appropriate authorities to seek, by all possible means, the ending of these illegal and demeaning sham marriages."
Dave Magrath, head of the UK Border Agency immigration crime team in the north west, said: "We are committed to tackling sham marriages and take action against those who try to falsify marriages in order to gain entry to the UK.
"We have specialist teams ensuring people are not able to benefit from breaking the UK’s immigration laws."
In a separate case, Burnley Crown Court heard 42-year-old Renata Kurejova wed at St Andrew’s Church when she was already married.
Kurejova, who lives in Gravesend in Kent, admitted perjury – by signing the marriage register – bigamy and assisting unlawful immigration. She was bailed until February 18, for a pre-sentence report.
Judge Beverley Lunt warned her: "I will be considering all sentencing options, including imprisonment."
At a separate hearing at the same court, brother and sister Martina Keselova, 21 and Martin Kurej, 22, both of Gravesend in Kent, admitted assisting unlawful immigration. Keselova had entered into the marriage and her co-defendant had been a witness, the court heard.
The pair were bailed until February 18, for pre-sentence reports.
Judge Beverley Lunt warned them she would consider all sentencing options including imprisonment.
In another case, Nadezda Mirgova, 26, a Czech national, pleaded guilty to assisting unlawful immigration to the UK and perjury. Sentencing has been adjourned to January 28.
